Disassembly systems obtain valuable parts from end-of-life products to remanufacture, reuse, or recycle them. This study deals with disassembly scheduling and presents a novel mixed integer programming model. Disassembly scheduling is the problem of determining quantity and schedule of items disassembled, held in inventory, sold, and disposed on capacitated resources over a planning horizon while satisfying at least a given service level. The model presented here includes a number of novelties including assignment of disassembly operations to parallel capacitated resources, consideration of costs to environment and demand for each level of items. We also present a problem testbed to be used for comparison of different algorithms and the generation mechanism. Results from a large experimental design using problem testbed are presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
