Recently work has been done about simulation and analysis of manufacturing operations combined with the communications network it operates with. However no such methodology exists in disassembly line context. In this paper, we attempt to enhance their approach and apply it for a disassembly line. To this end, we look at a disassembly line system as a combination of physical processing (performed by machines) and information processing (performed by computer systems), and formulate a model to analyze the system behavior and to obtain an optimal or near optimal solution that would maximize the system performance by minimizing the risk of down time due to network capacity related problems. A case example is presented to demonstrate the feasibility of the model’s implementation.
Today, growing amounts of waste due to fast consumption rate of products started an irreversible environmental pollution and damage. A considerable part of this waste is caused by packaging material. With the realization of this fact, various waste policies have taken important steps. Here we considered a firm, where waste Aluminum
constitutes majority of raw materials for this fir0m. In order to achieve a profitable recycling process, plant layout should be well designed. In this study, we propose a two-step approach involving Analytic Hierarchy Process (AHP) and Data Envelopment Analysis (DEA) to solve facility layout design problems. A case example is considered to demonstrate the results achieved.
