By conceptually comparing the two simulation methods, this thesis work investigates the limitations and possibilities of DES and combined model in plant simulation and visual components. Also look into which methods are best for teaching simulation and how they affect learning outcomes. A common benchmark was created to compare the DES and combined model, and a focus group session was held at University West to gather information from participants about the model's limitations and possibilities. Using an combined model instead of a DES model solves complex problems, while a hybrid approach allows existing models to be flexibly combined within a common large-scale context. According to the focus group, plant simulation is used to quickly build a conceptual model; however, one of the most concerning limitations of plant simulation is rarely close to real time application. Visual components, on the other hand, are the inverse of plant simulation; the models that are built arerelated to real-time applications, and the most significant disadvantage of visual componentsis time consuming
