Modeling and analysis of a closed-loop supply chain for aluminum engine manufacturing.

摘要

The closed-loop supply chain of an aluminum engine manufacturing operation is investigated. The push for the recycling of aluminum components in auto industry is motivated by profit incentives (i.e., the recovery of a valuable element) as well as by legal obligations (i.e., to comply with the requirements of the Extended Product Responsibility legislation), which have, therefore, given rise to the development of closed-loop supply chain.; The proposed research presents a planning model for the closed-loop process that includes purchasing, production, and end-of-life product collection and recycling/remanufacturing in the context of an aluminum engine manufacturing and recycling operation.; The model is a multi-echelon general integer linear program with the objective of minimizing the total costs in the network subject to structural and functional constraints. The model may be employed to make decisions regarding raw material procurement, production, recycling and inventory levels, and the transportation activities in the network.
