Simulation and Optimisation of a Failure-Prone Disassembly-Reconditioning-Assembly System

This paper deals with the simulation and optimisation of disassembly-reconditioning-assembly system (DRAS) taken into account random machines failures repairs. The proposed is composed one disassembly machine, two parallel structures, assembly machine stocks to store used products, components finished product. In this study a complete process in supply chain considered, which allows acquire disassemble storing reconditioning components, assemble selling product reply customers demand. objective determine optimal acquisition quantity products that maximises total profit. A mathematical model formulated on basis discrete flow express behaviour system. then simulated determined. Numerical results are presented discuss lost profit risk.
