A bi-objective MIP model for facility layout problem in uncertain environment

摘要: Facility layout problem (FLP) is one of the classical and important problems in real-world field industrial engineering where efficiency effectiveness are very factors. To have an effective practical layout, deterministic assumptions data should be changed. In this study, it assumed that we dynamic uncertain values for departments’ dimensions. Accordingly, each dimension changes a predetermined interval. Due to assumption, two new parameters introduced which called length width deviation coefficients. According these parameters, definition environment presented mixed integer programming (MIP) model developed. Moreover, objective functions their lower upper bounds calculated with four different approaches. It worth noting used minimize total areas, appropriate criterion appraise layouts conditions. Finally, solve some benchmarks literature test proposed and, based on results, present sensitivity analysis.
