Redundancy Allocation Combined with Supplier Selection for Design of Seriesparallel Systems

Designing highly reliable and economical systems is of interest in today’s competitive world. In this paper, enhancing system reliability through redundancy allocation is investigated, where the supplier selection is taken into account and redundant components are provided from appropriate suppliers with the most suitable offers such as discount on purchasing price of components, warranty length of components, things like that, so that the system reliability, profit and the warranty length proposed by suppliers are simultaneously maximized. The resulting multi-objective model is then solved with thewell-known compromise programming approach and the performance of the proposed approach is investigated through a numerical example.
