NSGA-II and goal programming approach for the multi-objective single row facility layout problem

Single row facility layout problem is the problem of arranging departments on a straight line. The main objective of the single row facility layout problem is to minimize the total material handling cost. However, it is not explanatory to use one objective. Hence, researchers pay more attention to model facility layout problems with qualitative and quantitative objectives. In this study, a weighted goal programming approach and a NSGA-II algorithm are proposed to solve multi-objective single row facility layout problem with the objectives of minimizing total flow distance and maximizing closeness rating scores. These objectives are taken into account for single row facility layout problem, for the first time, in this paper.
