    Digitalisering av arbetsflöde för avvikelsehantering på inköpt material: En fallstudie utförd på Nolato Cerbo AB i Trollhättan2020Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    A case study was performed at Nolato Cerbo AB in Trollhättan, with the objective to design a suggestion of a digital workflow for deviation handlingfor purchased material. The following questions were issued to fulfil the objective of the case study:

    • Is a workflow for deviation handling for purchased material possible to digitalize in order to facilitate documentation, traceability and information handling?

    • How should the workflow be designed in order to reach the involved personnel's requirements and needs?

    • Which advantages and disadvantages could emerge from the implementation of a digital workflow? To be able to map the current workflow and its issues, interviews with the involved departments were conducted. The interviews also brought up the employees' opinions of a digital workflow. A flowchart was created and waste in the workflow was identified. A benchmarking was performed at Varner Retail Logistics AB, to get an insight of how another company uses a digital workflow for deviation handling. A new flowchart for deviation handling for purchased material was created, where the manual parts of the flow were digitalized. After a test had been performed with concerned employees, it could be stated that the digital workflow will facilitate documentation, traceability and information handling. The requirements and needs for the involved personnel were also fulfilled. Advantages that the respondents consider can be achieved with the digital workflow was time save, no manual handling of paper, a faster distribution of information and that the correct information will be filled in from the beginning. Disadvantages that the respondents consider can emerge is that it will take some time for the employees to learn and adapt to the new way of working and the limitations of the mobileapplication. The conclusions that were drawn was that the digital workflow will be able to be used if it's designed according to the suggestion, although changes to the workflow might be performed in the future. There might also be employees at Nolato CerboAB which afraid of digitalization and changes. For the implementation to be successful, an education and information about the possibilities that digitalization brings will be required.

    Integrated Management Systems: testing a model for integration2011In: 14th Toulon-Verona Conference: Organizational Excellence in Service. Conference Proceedings / [ed] Jacques Martin & Claudio Baccarani., Alicante: University of Alicante , 2011, p. 22-35Conference paper (Refereed)
    Abstract [en]

    Management systems are widely used for creating order, minimising risks and for assuring performance. Management systems are in many occasions integrated since this has been found to be beneficial. In this paper a model for a fully integrated management system (IMS) based on the three axes of level, extent and scope of integration is tested for relevance. The studied system permits the integration of all relevant process dimensions. The research is only in a pilot stage, but the initial results are promising and indicate that there are advantages in using the process view as a base for identifying critical aspects to be managed. A review of the current situation for system integration is studied and the model is subjected to some tests using Sweden as a case. The background study shows that system integration still is limited, especially when comparing with a fully integrated IMS. The feedback from the organisations interviewed is positive and supports continued work with development of the model.

    On the microstructure of laser beam powder bed fusion alloy 718 and its influence on the low cycle fatigue behaviour2020In: Materials, ISSN 1996-1944, E-ISSN 1996-1944, Vol. 13, no 22, article id 5198Article in journal (Refereed)
    Abstract [en]

    Additive manufacturing of Alloy 718 has become a popular subject of research in recent years. Understanding the process-microstructure-property relationship of additively manufactured Alloy 718 is crucial for maturing the technology to manufacture critical components. Fatigue behaviour is a key mechanical property that is required in applications such as gas turbines. Therefore, in the present work, low cycle fatigue behaviour of Alloy 718 manufactured by laser beam powder bed fusion process has been investigated. The material was tested in as-built condition as well as after two different thermal post-treatments. Three orientations with respect to the building direction were tested to evaluate the anisotropy. Testing was performed at room temperature under controlled amplitudes of strain. It was found that defects, inclusions, strengthening precipitates, and Young’s modulus influence the fatigue behaviour under strain-controlled conditions. The strengthening precipitates affected the deformation mechanism as well as the cycle-dependent hardening/softening behaviour. The defects and the inclusions had a detrimental effect on fatigue life. The presence of Laves phase in LB-PBF Alloy 718 did not have a detrimental effect on fatigue life. Young’s modulus was anisotropic and it contributed to the anisotropy in strain-life relationship. Pseudo-elastic stress vs. fatigue life approach could be used to handle the modulus-induced anisotropy in the strain-life relationship. © 2020 by the authors. Licensee MDPI, Basel, Switzerland.

    Development of a process for environmental life cycle investigations2022Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    As a result of increasing interest in sustainable development, the subject of this report is the exploration of methods to analyse the environmental impact of car components. The project is conducted as a case study, and the theory section is a literature study where several scientific articles about life cycle assessment (LCA) and environmental analysis are examined alongside previously performed LCAs, books about the subject, and ISO standards. The ISO14040-series provides a structure for the basic methodology used in this report, both to organise the theory section as well as the resulting process.

    The theory concludes with a 7-step process for conducting life cycle investigations, primarily for car components. The first step contains the ISO standard’s requirements of defining goal and scope. Steps 2-6 then process the data collection of different phases during the life cycle and the 7th and final step is a compilation and calculation of the data.

    The developed process aims to provide a fast and simple way of analysing the environmental impact for a product as the development work is progressing. To validate the functionality of the process and to further refine the process, it is used to perform an analysis of energy use and CO2 emissions during the life cycle of an active car bonnet device. This validation includes definitions of goal, scope, functional unit, and a Process Flow Chart in the first step.Steps 2-6 includes the data collection for raw materials, additional processes, use phase, end-of-life, and the transports related to the manufacturing of the investigated product. The last step of the validation is to compile the product’s energy use and CO2 emissions. The study also provides a suggestion for a table, called Life Cycle Eco Data Table, to use when conducting a life cycle investigation using the process, to get an overview of the environmental data. The conclusion is that the developed process is easy to use and aspires to high quality as it is based on scientific research.

    A health‐related quality management approach to evaluating health promotion activities2012In: International Journal of Quality and Service Sciences, ISSN 1756-669X, E-ISSN 1756-6703, Vol. 4, no 1, p. 76-85Article in journal (Refereed)
    Abstract [en]

    Purpose – The purpose of this paper is to describe health promotion activities accomplished within a project and to measure the conditions for sustainable health within the case organizations. Also, the purpose is to test a previously developed measurement approach, which measures health-related quality management.

    Design/methodology/approach – A health promotion project currently being carried out at eight Swedish elementary schools has been studied. In earlier research a measurement approach was developed to measure health-related quality management. The approach was handed out to the co-workers at the eight different schools in the initial stage of the project. The leaders at the schools were informed of the results of their own school and the mean value of all the eight schools. The consistency and reliability of the statements within the approach was tested.

    Findings – A description of health promotion activities accomplished and planned within the project can be found. The results from the measurement of the health-related quality management in the eight schools are presented, together with the mean score of all schools. The test of the measurement approach is presented and discussed.

    Originality/value – A description of health promotion activities can help managers and project leaders to plan and carry out valuable health promotion activities in their striving for both sustainable health among the co-workers and efficient organizations. This measurement approach can help managers and project leaders to measure the effects of the health promotion activities

    Change of the Quality Management culture through health-promotion activities?2014In: Total Quality Management and Business Excellence, ISSN 1478-3363, E-ISSN 1478-3371, Vol. 25, no 11-12, p. 1236-1246Article in journal (Refereed)
    Abstract [en]

    There is great demand for workplace health-promotion programmes that improve co-worker health and provide a return on investment, which is due to the continuous escalation of care costs and the prioritisation of co-worker health by businesses. Early research found that organisations that have achieved good co-worker health with low sickness absence through their conscious and well-structured work were also working according to Quality Management. Health-promotion interventions are possible in every organisation, but before starting a health-promotion programme it is necessary to analyse the organisation and especially its culture. The purpose of this paper is to measure in what way health-promoting activities influence the Quality Management culture, particularly the health-related values 'Leadership commitment' and 'Participation of everybody'. A comparison between the Quality Management culture before starting a health-promotion project and the results a year later is presented. The results show that health-promotion activities do not affect the Quality Management culture, at least not from a year perspective. On the other hand, the results show that health-promotion activities can affect co-workers' perception of their health. © 2014 © 2014 Taylor & Francis.

    Clogging and lump formation during atmospheric plasma spraying with powder injection downstream the plasma gun2007In: Journal of thermal spray technology (Print), ISSN 1059-9630, E-ISSN 1544-1016, Vol. 16, no 4, p. 512-523Article in journal (Refereed)
    Abstract [en]

    This study aimed to numerically and experimentally investigate lump formation during atmospheric plasma spraying with powder injection downstream the plasma gun exit. A first set of investigations was focused on the location and orientation of the powder port injector. It turned out impossible to keep the coating quality while avoiding lumps by simply moving the powder injector. A new geometry of the powder port ring holder was designed and optimized to prevent nozzle clogging, and lump formation using a gas screen. This solution was successfully tested for applications with Ni-5wt.%Al and ZrO2-7wt.%Y2O3 powders used in production. The possible secondary effect of plasma jet shrouding by the gas screen, and its consequence on powder particles prior to impact was also studied.

    The right evaluation method - an enabler for process improvement2013Conference paper (Other academic)
    Abstract [en]

    This paper aims at describing the procedure where an alternative evaluation process was developed to support the improvement of both welding and weld quality evaluation. Welded structures are important when striving for reduced fuel consumption due to vehicle weight. Hence good control of the fabrication process is critical to keep welding performance on target, avoiding waste in terms of added weight and overproduction. The resulting distribution of weld weight has shown to be an important control parameter in the sense of keeping cost down.

    To identify the causes for deviations between actual and theoretical weld weight, information about the weld was needed. The currently used evaluation method showed not to be capable of giving the information needed. It was necessary to know the throat size as well as weld geometry. The current evaluation method introduced more variation due to the measurement than the actual fabrication process itself, leading to drift of process target and overproduction.

    To fulfil the need of information, that different functions within the company had, a PULL-approach was used. The information need, information presentation and sequence were outlined for each information receiver individually. An alternative measurement method was developed and named WIA – Weld Impression Analysis. The method consists of two parts; creating the replica and analysing the shape in an image analysis program.

    The method was tested to see if it was capable of delivering accurate and precise measurements, satisfying repeatability and reproducibility requirements for this particular situation. A thorough measurement system analysis was carried out. The measurement system assigned 98.98% of the total variation to part-to-part variation corresponding to long-term process variation. The variation that stems from taking the impressions and preparing them was as well investigated, also showing satisfying results. Finally it was investigated if the impressions reflect the true shape of the welds accurately. The results showed a tendency of slightly higher cross sectional areas in the range of 0-3 %. This however indicated that the accuracy of the measurement system was sufficient for its purpose.

    The PULL-approach generated a sufficient method which enabled the possibility to perform process improvement and gain large production cost savings.

    A Case Study Initiating Discrete Event Simulation as a Tool for Decision Making in I4.0 Manufacturing2021In: Lecture Notes in Business Information Processing, ISSN 1865-1348, E-ISSN 1865-1356, Vol. 414 LNBIP, p. 84-96Article in journal (Refereed)
    Abstract [en]

    Smart manufacturing needs to handle increased uncertainty by becoming more responsive and more flexible to reconfigure. Advances in technology within industry 4.0 can provide acquisition of large amounts of data, to support decision making in manufacturing. Those possibilities have brought anew attention to the applicability of discrete event simulation for production flow modelling when moving towards design of logistics systems 4.0. This paper reports a study investigating challenges and opportunities for initiation of discrete event simulation, as a tool for decision making in the era of industry 4.0 manufacturing. The research has been approached through action research in combination with a real case study at a manufacturing company in the energy sector. The Covid-19 pandemic fated that adjusted and new ways of communication, collaboration, and data collection, in relation to the methods, had to be explored and tried. Throughout the study, production data, such as processing times, have been collected and analyzed for discrete event simulation modelling. The complexity of introducing discrete event simulation as a new tool for decision making is highlighted, where we emphasize the human knowledge and involvement yet necessary to understand and to draw conclusions from the data. The results also demonstrate that the data analysis has given valuable insights into production characteristics, that need addressing. Thus, revealing opportunities for how the initiative of introducing discrete event simulation as an anew tool in the wake of industry 4.0, can act as a catalyst for improved decision making in future manufacturing. © 2021, Springer Nature Switzerland AG.

    Förslag på utformning av en monteringscell för att öka produktionskapaciteten: för VP1-pumpar på Parker Hannifin AB2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This work has been carried out at Parker Hannifin in Trollhättan and is describing concept work for design proposals of an assembly cell in which a hydraulic pump is produced. The current assembly cell does not have a high enough capacity to meet a rising demand. The aim of this work was to propose a balanced assembly cell whose capacity increases with increase in the workforce. The goal was to present a model of an assembly cell that can achieve a production capacity of at least 200 pumps per week.By observing the current assembly, and study the various operations time duration, different time balancing charts were created. Unlike the current time balancing charts the operations for calibrating and controlling the pumps functions in a test rig were now included. Various concepts were created and discussed with stakeholders and were followed by revisions of the concepts before a screening. The concepts were screened down to two concepts, which were modeled in full scale to allow for evaluation according to the working method Production Preparation, 2P. After that, a concept point matrix was created and the concepts were rated with the use of the evaluation of the models.The concept recommended to Parker is called "Two-sided assembly" and is a concept where the majority of the sub-assemblies for building a VP1 pump is made on one side and then transported on a roller conveyor to the other side where a smaller amount of sub-assemblies is made to be followed by the final assembly.The concept with the examples of time balancing charts results in a production capacity of 227 pumps per week. The concept is flexible and can be adapted to several workflow standards and there is potential for further development if the concept is deemed suitable to implement by Parker.

    Learning for quality in the SPA-industry: a quality café study2013Conference paper (Refereed)
    Abstract [en]

     This paper reports a study carried out in the Swedish SPA-industry. The purpose has been twofold. The first purpose was to explore quality dimensions for SPA-hotel staff. The second purpose was to investigate the usability of the quality café method for quality development. Thus, the second purpose is methodological to its nature.

    Methodology/ApproachThe quality café is a novel method which is based on the world café method combined with quality management tools. Seven quality cafés were carried out at seven different SPA-hotels. The participants were employees from different departments of the hotels. The results are related to a theoretical framework based on organisational learning theory.

    FindingsThe quality café method is found to be a useful tool for gaining in-depth knowledge pertaining to quality management. Moreover, quality dimensions for SPA-staff  have been defined as clearness, security, participation and meaningfulness. Based on the dimensions questionnaires have been developed.

    Research Limitation/implicationOne important implication is that the quality café has been found to be a usable method for quality development. This constitutes a methodological addition to the array of tools used for research as well as for practice of quality management. Furthermore, the dimensions defined provide further understanding into the meaning of quality in the SPA-industry. A limitation is that the study was only performed in one industry and in one country. Further research is consequently needed for assessing the generalizability of the findings.

    Originality/ValueAlthough the SPA-industry is expanding in most parts of the world little research has been carried out regarding quality in this sector. The quality café is an original and novel method which has proved its usefulness in the current study.

    Abstract [en]

    The purpose of this study was to examine the possibility of integrating the World Café method with the affinity diagram tool from quality management. The proposed combination is called the Quality Café. Quality Cafés were carried out at seven spa hotels, one municipality and two student organisations. The cafés were assessed with feedback seminars and questionnaires. The findings show that the method was appreciated by the participants. It contributed to profound dialogues with deepening insights, which stimulated creativity, increased understanding for quality issues and allowed a more holistic view. In addition, the method was experienced as enjoyable and in itself creating coherence. The findings were related to organisational learning theory and several connections were found. The Quality Café should be a useful method for researchers in social science as well as for practitioners. A limitation is that determining the specific effects of the Quality Café method compared to the original World Café is difficult.

    On your marks – but are you ready?: Like marriage, six sigma needs commitment2011In: Development and Learning in Organizations: An International Journal, ISSN 1477-7282, E-ISSN 1758-6097, Vol. 25, no 6, p. 26-28Article, book review (Other academic)
    Abstract [en]

    Purpose – Reviews the latest management developments across the globe and pinpoints practical implications from cutting-edge research and case studies.

    Design/methodology/approach – This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context.

    Findings – Assessing suitability for big step in learning to improve. Any organization which decides to implement a six sigma system to improve business leadership and performance should not underestimate the enormity of the initial step and lasting commitment it is about to make. A little like going into marriage, perhaps – it is going to be wonderful if it succeeds but the people involved have to be sure they are ready to take the step. It is likely that attitudes and behaviors will have to change and, like marriage, six sigma can be costly so it is not advisable to take a half-hearted approach at the beginning.

    Practical implications – Provides strategic insights and practical thinking that have influenced some of the world's leading organizations.

    Originality/value – The briefing saves busy executives and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to digest format

    Organisational learning and Six Sigma deployment readiness evaluation2011In: International Journal of Lean Six Sigma, ISSN 2040-4166, E-ISSN 2040-4174, Vol. 2, no 1, p. 23-40Article in journal (Refereed)
    Abstract [en]

    Purpose

    The purpose of this paper is to provide a greater understanding of organisational learning in connection with assessment of Six Sigma readiness. Different forms that a possible deployment can take in the organisation's context based on the degree of readiness are explored.

    Design/methodology/approach

    The empirical data are derived from 12 in‐depth semi‐structured interviews of selected employees having different functions in the studied organisation, a global distribution system and information technology (IT) solutions provider to the travel and tourism industry. In addition, they include participant observation and documentation. The interview questions were built based on a modified version of Kettinger and Grover readiness assessment framework.

    Findings

    The study shows that organisational learning can provide a useful framework for assessing Six Sigma readiness in an IT organisation. A synthesized model is proposed combining the frameworks of an adapted Kettinger and Grover model and the core disciplines of the learning organisation. Further, the results suggest that having Six Sigma as a company‐wide strategy may not prove useful or suitable in the current context. However, the analysis shows that having Six Sigma as an improvement programme provides a structure for the improvement work and the define, measure, analyze, improve and control methodology is needed to address some current inefficiencies and problems.

    Research limitations/implications

    This is a single case study and the possibility of generalising this finding to other contexts remains uncertain. Therefore, more research is needed. The procedure of using organisational learning as an assessment framework for Six Sigma readiness has been shown to be useful.

    Practical implications

    Implementing Six Sigma means a large investment and therefore it is important to make the right deployment approach. Having one integrated readiness assessment model should be useful for companies when assessing their readiness.

    Originality/value–

    Knowledge of a Six Sigma readiness evaluation in an organisational learning context should be valuable for many organisations. In addition, research regarding Six Sigma in software companies is limited.

    Aesthetic service quality: a study of a symphony orchestra2017In: Total Quality Management and Business Excellence, ISSN 1478-3363, E-ISSN 1478-3371, Vol. 28, no 3-4, p. 318-330Article in journal (Refereed)
    Abstract [en]

    The purpose of this paper is to explore service quality in classical music, to relate the findings to the essence of Beauty that Kant, Plato and others describe and to discuss the implications for practice and research regarding aesthetical organisations. Some of the views of Beauty held by Plato and Kant are described and related to the theories of service quality, particularly the fundamental premises of the service dominant logic of marketing. An empirical study has been carried out at the Gothenburg Symphony Orchestra. In-depth interviews with members of the orchestra have provided qualitative data that have been analysed. The musicians’ views of quality in classical music are described. The findings are related to the philosophical theories of beauty and to the service quality theory. A model of quality dimensions in classical music is proposed. The findings of the study provide a vantage point for better understanding of the relationship between aesthetics and service quality. Service quality in music has not previously been studied and related to aesthetical theory. A limitation is that the study has only been carried out in one orchestra in one country. For managers of organisations with aesthetic activities, the study provides guidance into how service quality can be seen and handled.

    Customer perceptions of quality: a study in the SPA industry2016In: European Business Review, ISSN 0955-534X, E-ISSN 1758-7107, Vol. 28, no 6, p. 657-675Article in journal (Refereed)
    Abstract [en]

    Purpose - The purpose of this study is to explore dimensions of customer perceptions of factors important for a quality experience in the SPA industry and to assess service quality implications for these dimensions. Design/methodology/approach - The empirical study involved seven Swedish SPA hotels. The first part was qualitative, consisting of seven focus-group interviews with hotel guests. In addition, service providers’ perceptions of customer quality were collected through seven quality cafes. The qualitative parts were analysed with the constant comparative technique from the grounded theory approach. Based on the findings from the interviews, a questionnaire was delivered to 400 randomly accessed women. The responses were analysed with exploratory factor analysis and cluster analysis. Findings - The focus-group interviews showed that the customers’ perception of quality could be expressed in the following dimensions: physical effects, mental effects, pleasure and flexibility. The dimensions for customer quality seen from the staff’s perspective were treatments, climate and the SPA facility itself. The exploratory factor analysis defined the following underlying factors: enjoyment, treatments, practicality, fitness, cost and calm. The cluster analysis resulted in four groups of customer profiles: the more of everything group, the enjoyers, the savers and the fitness freaks. Research limitations/implications - Alimitation is that the study has only been carried out in one country. The main implication for research is a better understanding of quality dimensions and perceptions of service quality in the SPA industry. Practical implications - The study provides a comprehensive insight into the dimensions of quality for SPA visitors. Moreover, four distinct groups of customers have been identified. This knowledge should be useful for SPA managers. Originality/value - Only limited amounts of research have previously been carried out in the SPA industry. The paper provides a framework depicting perceptions of quality dimensions in SPA hotels.

    The effects of quality management, a survey of Swedish quality professionals2005In: International Journal of Operations and Production Managment, Vol. 25, no 10, p. 940-952Article in journal (Refereed)
    Abstract [en]

    Purpose – In this study, the effects of the different models and tools of quality management are examined. The purpose is to identify differences in the effects generated by different qualitymanagement models and tools.

    Design/methodology/approach – A questionnaire was mailed to 500 Swedish quality professionals. The questions concerned their companies’ adoption of the values of TQM, the use of the models and tools of TQM and the effects they notice. Correlation analysis and multiple regression analysis were carried out.

    Findings – The findings show that there is statistical correlation between the adoption of the values of TQM and successful quality management. The usefulness of the Swedish Quality Award, the European Quality Award and ISO 9000 as well as several of the quality management tools is also indicated. Regarding ISO 9000 specific effects have been found.

    Research limitations/implications – A limitation of the study is that the financial outcomes of the quality management practices are not measured but only the managers’ perceptions of effects produced. The implication for further research is an increased knowledge of the different effects of the quality management practices and the significance of the values, particularly three values that were included in the multiple regression models.

    Practical implications – The specific findings on the effects of ISO 9000 are useful for managers when implementing the standard. The results of the study also indicate the importance of emphasising the values for successful quality management.

    Originality/value – This study has provided more detailed knowledge of the effects of the differentquality management practices, particularly of ISO 9000.

    The Quality Café as a method for organisational learning and quality development2013In: PROCEEDINGS OF THE INTERNATIONAL CONFERENCE ON MANAGEMENT, LEADERSHIP AND GOVERNANCE / [ed] Vincent Ribiere,Lugkana Worasinchai, Bangkok: The Institute for Knowledge and Innovation , 2013, p. 203-208Conference paper (Refereed)
    Abstract [en]

    This paper reports a study into the usefulness of a method called the Quality Café. The method is based on the World Café method which has been supplemented with the quality management tool,

    affinity diagrams. The purpose of this paper is to investigate The Quality Cafe as a method for organisational learning and quality development. The paper is based on theory from quality management and organisational learning. A framework depicting quality man-agement as a system of components of different profundity is presented. In the study the possibility of integrating more profound aspects in one of the superficial tools, the affinity diagram, is assessed. A case study has been carried out in which a Quality Café was performed in a Swedish SPA-hotel. The results have been as-sessed for their usefulness for the company as well as for research. It is found that the method was useful in both regards in this specific case which indicates its us-ability. Nevertheless further research is needed to assess the general usefulness of the method.

    Developing a neuropsychological measurement to capture workplace learning2016In: Journal of Modelling in Management, ISSN 1746-5664, E-ISSN 1746-5672, Vol. 11, no 3, p. 783-801Article in journal (Refereed)
    Abstract [en]

    Purpose - The purpose of the paper is to examine variables to be included in a measurement instrument which measures workplace learning related to recent research into quality management and brain functioning. Design/methodology/approach - A literature review was conducted, investigating measures of workplace learning as well as the connections between brain functioning and management. Further studies will use the brain integration scale to compare levels of brain integration with measures of workplace learning. Findings - The variables “empathy”, “presence and communication”, “continuity”, “influence”, “development”, “work-integrated learning” and “flow” were found to be relevant from the literature review to be tested for inclusion in the measurement instrument. A measurement model with these variables included has been developed. Research limitations/implications - This paper is conceptual in its nature. Empirical studies are needed to validate the propositions. Practical implications - The proposed measurement instrument can be used by managers to gain insight into underlying mechanisms in the organizational culture that influence employees’ learning and potential for development. Thus, it can aid managers to achieve profound learning in their organizations, which is necessary for continuously maintaining high quality of products and services. Social implications - For society, the implementation of the proposed measurement instrument in companies could lead to better health and higher job satisfaction among employees. Originality/value - Traditional ways of measuring working environment are rarely connected to brain functioning of the employees. Only requiring small resources, this approach adds to an understanding of underlying mechanisms.

    "Fåglar i vägen": En studie av åtgärder för minskning av olycksrisk för kollision med fåglar på flygplatser2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Kollisioner mellan flygplan och fåglar har inträffat i över 100 år och den första kollisionen med dödlig utgång skedde 1912. Den ökande flygtrafiken sedan början på 1900-talet har lett till allt fler kollisioner och dödsfallen inom civilflyget var mellan 1988-2015 över 200 människor. Förutom dödsfall orsakar kollisioner dyra reparationer, uppskattat till 1.2-4 miljoner dollar, samt förseningar för resenärer.Syftet med studien är att presentera lösningsförslag för att minska risken för kollision mellan flygplan och fåglar vid Trollhättan Vänersborg flygplats. Minskar fågellivet kring flygplatsen bidrar det till att skapa en säkrare miljö för resenärerna samt en säkrare arbetsplats för flyg och markpersonalen.För denna studie valdes aktionsforskning som metod. Metoden har likheter med fallstudier och kartläggningar som inleds på liknande vis. Studien är i huvudsak kvantitativ med några få inslag av kvalitativ art.För att systematiskt förstå och sätta sig in i problematiken tillämpades Sex Sigma verktyget DMAIC, som med hjälp av litteraturstudier, samt intervjuer skapade en god grund för det fortsatta arbetet. Datainsamlingen analyserades och viktades ut efter kravspecifikationen för att ta fram de lämpligaste lösningsförslagen åt Trollhättan Vänersborgs flygplats AB. Det visade sig att förslag som högre gräs kring landningsbanan och att skapa en näringsfattig miljö var de två lösningsförslagen som fick högst betyg. De två förslagen har visat sig synnerligen effektiva på andra flygplatser och dessa i kombination med en list kring landningsbanan är de lösningsförslag som anses mest lämpliga för Trollhättan Vänersborgs flygplats AB.

    Improving Supply Chain Material Flow: A case study on Nouryon’s Internal Transfer Process2024Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Internal transfer processes in a supply chain involves moving goods or materials within the same organization, encompassing inventory, raw materials, or finished products between different departments, warehouses, or production facilities. The objective is to enhance material flow and coordinate efficiently across the organization, leading to improved overall supply chain performance. Essential components of these processes include planning, order processing, inventory management, and logistics, all focused on optimizing the movement of goods within the company's network.

    For the case company, Nouryon, the challenge lies in managing the internal transfer process, marked by inconsistent lead times. Currently, there is no standardized procedure in place, and ad-hoc measures taken so far have proven ineffective in the long term.

    The project aims to implement a new standard process within the system and rectify the identified issues. Ultimately, this initiative is also centered around enhancing customer satisfaction, as the customer's contentment hinges on the seamless flow of the process. The purpose of this study is to examine ways to improve the internal transfer process within the organization. The research was carried out in partnership with Business Planning Managers and Executives at Nouryon across the entire organization on a global scale.

    To achieve the goals of the study and answer the research questions, a comprehensive approach, including literature review, interviews, observations, and document collection, was undertaken. The internal transfer process from Stenungsund to the US was analyzed using the Six Sigma (DMAIC) methodology, identifying lead times as the primary bottleneck in the US. However, the Six Sigma concept was deemed inapplicable to Japan's internal transfer process, which did not face lead time issues. Instead, the analysis revealed bottlenecks in Japan, including excessive inventory, overproduction, and excessive material transportation. Addressing Japan involved applying the Lean Methodology, specifically focusing on the MUDA principle to reduce waste.

    The project resulted in the identification of key improvement recommendations that can contribute to enhancing the internal transfer process. Recommendations for US is improving lead times, implementing dedicated time slots, extend CGM shipments' lead time and update master data to improve the internal transfer process and boost customer satisfaction. Recommendations for Japan is implementing Lean Methodology with the key principle JIT aiming for for increased efficiency and reduced waste (MUDA).

    Åtgärdsförslag till Sansera Sweden AB för att uppfylla kraven i kvalitetsstandarderna ISO 9001:2015 och IATF 16949:20162017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In this thesis, a Gap Analysis has been performed to find out how Sansera's quality management system meets the new requirements in the standards ISO 9001:2015 and IATF 16949:2016. The aim of the thesis is to make suggestions for actions that Sansera needs to take in their current quality management system in order to be certified according to the latest standards. In the Gap Analysis that was established, the standards ISO 9001:2015 and IATF 16949:2016 were compared to the previous standard ISO/TS 16949:2009 to find out what requirements are new. The requirements were then compared with Sansera's quality management system to identify the company's current situation. Based on the results of the Gap Analysis, the extent of the gaps was identified in Sansera's quality management system. In the study a benchmarking was performed against a company with similar processes like Sansera. The benchmarking was performed to verify if the methodology in this study is appropriate for its aim. The result of the benchmarking confirmed that the methodology used in the study is appropriate. Several of the requirements in the standards ISO 9001:2015 and IATF 16949:2016 requires that there should be documented information for the process that the requirement covers. The result of the Gap Analysis showed that a recurring reason for several of the gaps was that Sansera did not have the documented information for its processes required by ISO 9001:2015 and IATF:2016. Requirement 4.2.2 proved to be the most critical requirement because it can only be fulfilled if all other requirements containing requirements for documented information are fulfilled. In the study the suggestions for actions are presented to the gaps in Sansera's quality management system which is fulfilled by half, small part or not at all. The suggestions for actions are considered to be able to close the gaps in Sansera's quality management system. In order for Sansera to fulfill the gap regarding the lack of documented information, the company is recommended to update their current document management system, it is assumed to facilitate the introduction of the suggested procedures regarding documented information.

    Konceptframtagning av mätmetod för kuggkransar2024Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [sv]

    Examensarbetet utfördes på Parker Hannifin Manufacturing Sweden AB i Trollhättan och fokuserade på konceptframtagning för att etablera en ny mätmetod. Inom en av Parker Hannifins produktionsgrupper skapas kuggkransar i olika storlekar för axelpaket. Efter bearbetning är det avgörande att kontrollera och mäta dessa kuggkransar för att säkerställa att de ligger inom specificerade toleranser. Detta ansvar ligger på operatörerna inom tillverkningsgruppen. I nuläget kontrolleras kuggkransarna med hjälp av en osäker fixtur och utan standarder.

    Metoder omfattar flertal steg. Informationsinsamling som inkluderar litteraturstudier, observationer och intervjuer. Därefter kreativ problemlösning som involverar att generera många potentiella lösningar på kort tid och sedan metodiskt utvärdera dem för att välja de mest effektiva. MSA, en förkortning för mätsystemsanalys, används för en noggrann utvärdering av mätprocessen för att identifiera variationer i dagens mätmetod. Riskgenomgång för att identifiera, bedöma och hantera risker i samband med införandet av den nya metoden. Verktyg som Process Failure Mode and Effects Analysis (PFMEA) används för att hantera dessa risker.Konceptutveckling används för att granska och validera utformade produkter och säkerställa att de möter projektets mål. Under processens gång genererades över 105 000 olika koncept, som sedan sållades ner till 16 och ytterligare till 6 med hjälp av CAD-programmet Autodesk Inventor.

    Resultaten från detta koncept visade potential för ökad precision och minskad variation i mätningsprocessen. Ett slutgiltigt koncept specificeras med instruktioner och komponenter. Det konceptet som rekommenderas till Parker Hannifin benämns ”Koncept H” och består av två lasrar som mäter djupet och bredden i 7 lätta steg.Slutsatsen av arbetet visar på behov av framtida utveckling och implementering av ”Koncept H” hos Parker Hannifin för att förbättra och effektivisera mätningsprocessen. Det tas även upp två andra möjliga lösningar och förslag på förbättringar av dagens mätmetod genom instruktioner och standarder.

    How an Enlarged Maintenance Function Affects the Performance of Industrial Maintenance and Maintenance Services2011In: Maintenance performance measurement and management, MPMM2011: 13-14 dec, Luleå / [ed] Galar d, Parida A, Schunnesson H, Kumar U, Luleå: LTU , 2011, p. 107-112Conference paper (Refereed)
    Abstract [en]

    Today, many companies struggle with maintenance work established by pre-requisites during purchasing, installation and start-up of plants, systems and machines. In search for improvements in existing maintenance organizations, it´s easy to conclude that they look like and is a direct consequence of previous engineering decisions and activities.

       Maintenance is, however, performed in the operation phase with weak coupling to what created it. Using an empirical knowledge base, several examples of this narrow view on maintenance is given along with the consequences it results in today.

       It is argued, that the increasing need to create and preserve knowledge will be the driver for change and the main contribution to an enlarged and more efficient maintenance function. Improvements are pointed out using references to the leading actors creating the frontier today where most companies could be tomorrow. The paper hopefully will contribute to how maintenance processes and activities are being designed, set-up and carried out.

    Abstract [en]

    This thesis is comprised of an investigation of equipment effectiveness at the company Produce AB (fictitious name) at two machine cells, Alfa, which consists of four millers and Beta, which consists of four lathes. The company is a subcontractor of metal products to three different business areas and consists today of 100 employees. By measuring the actual time the machinery process goods for the customer the company have identified low machine utility as a problem in the production. With this investigation, they therefore want to identify the causes of this problem in order to improve the business and become more competitive. The approach for this investigation is based on the methodology within Six Sigma where the DMAIC model has been used. Quantitative data collection occurred during ten days with the use of an operator template, where duration and cause of machine downtime was noted. Qualitatively, unstructured, semi-structured and fully structured interviews have been used to analyze the root causes for machine downtime that was identified following the quantitative data collection. The main part of the theoretical framework for this thesis includes total productive maintenance and overall equipment efficiency, which was used to map and calculate the current state of the equipment efficiency. Other theoretical frameworks are Lean, material- and production planning, resource utility and variations. These theories were used to analyze the result and give suggestions for improvement. The calculated equipment efficiency varies between both the cells and the machines within the cells. In the Alfa-cell, values vary between 52 and 80 per cent and in the Beta-cell between 37 and 57 per cent. The significant causes for machine downtime were identified as lack of personnel, long set-up times, machinery waiting for operators, differences in processing time between cycles and machine breakdowns. From this, suggestions for improvement were developed. The suggestions included employment of addition personnel, reduction of set-up times, introduction of an Andon-system and elimination of processing time differences. In general, the authors of this thesis can see that the company has a will to improve, but the work with improvements has been suffering since the production is behind, compared to what the customer demands. A lack of resources and short term-thinking are therefore considered two of the things that most affect the company's possibilities to maintain a competitive business.

    Airdrome Aviation Safety Climate Questionnaire (ADASCQ): Utveckling av enkätinstrument för att mäta organisationsklimat för hög flygsäkerhet vid flygplatsarbete2017Report (Other academic)
    Abstract [sv]

    Att de flygplan som används i flygtrafiken är oskadade är självklart en viktig förutsättning för flygsäkerheten. När flygplanen befinner sig på mark sker en mängd olika operativa moment i och omkring planen, ofta under tidspress, och som involverar ett stort antal individer, organisationer, och olika typer av teknisk apparatur. För att flygplanen inte ska komma till skada i dessa operationer måste de utföras enligt tydliga procedurer, med kunskap och noggrannhet och med hög grad av koordinering av olika moment och aktörer. Detta ställer höga krav på de formella säkerhetssystemen. Men flygsäkerheten påverkas även av individuella och sociala fenomen. De sociala förutsättningarna handlar om hur sociala normer ser ut och utvecklas på arbetsplatsen. Här blir fenomen som säkerhetskultur och säkerhetsklimat betydelsefulla. En förutsättning för att kunna arbeta med att utveckla flygsäkerhetsklimatet så att det än bättre stöder en hög flygsäkerhet vid flygplatsarbetet är att man kan skaffa sig en uppfattning om kvaliteten på säkerhetsklimatet. Är det högt eller lågt? Vilka är de svaga punkterna, som behöver åtgärdas? Och vilka är de starka sidorna, som man bör gynna ytterligare? Ett sätt att mäta säkerhetsklimatet är genom enkät. Denna delrapport ger en teoretisk bakgrund till begreppet säkerhetsklimat och beskriver sedan utvecklingen av ett enkätinstrument för att mäta flygsäkerhetsklimat vid flygplatsarbete; Airdrome Aviation Safety Climate Questionnaire, ADASCQ.

    Abstract [en]

    Today's industry is subject to fierce competition. This requires constant business development and continuous increment in product variety to meet customer requirements. Management Tools such as Lean Production, which focuses on a continuous reduction of waste in all parts of the company, plays a key role in today's industry. In order to reconcile the continual improvement of the organization's well-being requires a structured approach in the form of organized improvements.  The work carried out at Swegon AB in Kvänum identifies possible changes concerning the wrapping process in efficiency improvement and resource saving purposes. The company produces air handling units and fans for indoor use. The products are used in stadiums, hotels, hospitals, airports, universities and private housing.  Today’s wrapping process is perceived as ineffective. The company sees potential for improvement in transportation cuts, in minimizing physical and business management steps and thus reduce the need for storage space and buffers. Along with a restructuring, that focuses on improving material flow and layouts, large parts of the production is changed, from a function-oriented to an increasingly process-oriented structure. If the proposed changes are to be implemented this most likely occurs in conjunction with the rebuilding.  The work was initiated by a comprehensive survey of today's wrapping process. The empirical collection began through interviews, observations and process mapping. The survey was completed by applying the fishbone diagram, where the root causes of the identified problems were structured.  Continuous literature studies were conducted to substantiate the used methods. The theory deals primarily with lean production with focus on waste and standardization. Suggestions for improvement were generated continuously in close cooperation with technicians and production staff. The focus was on reducing non-essential steps in the process. This work results in four proposed changes: scanning, layout changes and kitting. These changes give rise to a reduced need of resources and an increased quality towards customers. Additionally, the proposals improve opportunities for standardization of the process in the future. Date
