An Integrated Knowledge Management Framework for Sustainable Supply Chain using a system dynamics Model for POGC

Supply chains have experienced rapid growth in recent years. Focusing purely on economic performance to optimize costs or return on capital can no longer guarantee development or sustainability in the chain. Hence, the concepts of green SCM and SSCM emerged to emphasize the importance of social and environmental concerns along with economic factors in supply chain programming. Using the SD method and considering KM , this study investigates the variables related to this topic and the variables of sustainable supply chain management and it determines the relationships between these variables and their impact on the research purpose. To achieve this, first, previous studies are reviewed, and the relevant variables are extracted and finalized according to the experts. Next, SD modeling is designed and various scenarios are defined by changing the effective values of the system. Eventually, several policies are presented to achieve the optimal situation. The optimal values for the ten main influential variables are extracted according to the expert opinion and the effects shown in the model are determined by these changes.
