multi-criteria approach for remanufacturing model in a disassembly-to-order system

We present a disassembly-to-order system applied in a multi-period environment where the products are taken back from the last user and/or collectors, disassembled for the retrieval of reusable items and resold (or used) in order to meet a certain level of demand for components or subassemblies. The surplus items are recycled, stored for use in subsequent periods or properly disposed of while the surplus products are only stored for subsequent periods or disposed of. We assume that the items have finite shelf lives after which they must be disposed of. Another assumption has to do with space limitation. Thus, it is not always possible to store all items in inventory even if they have positive shelf lives. We model the problem using goal programming (GP) so that there is a balance between environmental as well as economical issues. A numerical example is provided to illustrate the methodology.
