Simulation Based Multiple Disturbance Evaluation in a Green Closed-Loop Supply Chain

Disturbances are inevitable and ubiquitous part of a supply chain, especially in the supply chain of electronic equipment. When the budget is limited, the evaluation of these disturbances to prioritize and try to prevent them became more critical. This study proposes an overall disturbance evaluation model to assess the uncertainty of the closed-loop supply chain of a specific electronic device. The model is developed using ARENA-based discrete event simulation methods and aims to address the effects of disturbances in the process of the supply chain before and after implementing precaution measures. The model is constructed on a green closed-loop supply chain with five categories of disturbances derived from suppliers, manufacturers, and customers. Finally, four scenarios with different levels of exposure to disturbances are investigated to test the validity of the proposed approach. The findings could facilitate the disturbance management process of the evaluated supply chain.
