Economical Analysis and Optimization of Recovery Processing Policies about Discarded Product

摘要

On the foundation of analyzing the closed loop logistics chain of product with multi-lifecycle, the connotation of environmental value is set forth, recurring to such conceptions as supply chain and value chain.The plotting rules about disassembly tree are discussed in detail. The reachable matrix R of components' disassembly is introduced into distinguishing if disassembly is needed, in combination with disassembly-deciding vector X. Furthermore, the arithmetic of disassembly cost is put forward. And the cost-benefits of components'reusing, materials' recycling, safety disposing are dissertated based on the activity-based costing. Then the 0- 1 goal-programming model on product recovery processing is established, with components' demotion calculated.In addition, takinq the PC's recovery Drocessinq for example, we Dut it into application.
