Modeling and evaluation of supply chains with GSPN components
Gabriel Alves, Paulo Maciel, Ricardo Lima · Performance Evaluation Methodolgies and Tools · 2007
The global competition between manufactures and the requisition of high service levels for customers, led companies to recognize the relevance of supply chain management. The outbound logistics deals with the transportation and storage of finished goods from the end of the manufacturing to the customers. This paper proposes the use of predefined Petri nets components to model and evaluate this activity. Aiming supporting a modeling process based on library's components, a modeling tool was implemented. It allows one representing supply chains by considering a high-level model, which is further converted into a Generalized Stochastic Petri Nets (GSPN) model, regarding librarySs components. This tool was also integrated with TimeNET, a well known Petri net tool, aiming computing model's metrics. Afterwards, it is presented a real case study conducted in a Brazilian meat processing industry.
