A simulation optimization approach for facility layout problem

In order to response effectively to the changes in product mix and volume, manufacturing facility need to be changed frequently. So the facility layout design becomes critical. In the paper, a simulation optimization methodology is proposed to resolve the facility layout problem. Firstly, candidate facility layout schemes are suggest by GA that automatically guides the system towards better solutions. Secondly, Simulation models are used to evaluate the performance of candidate facility layout schemes, the results of evaluation are returned to the GA to be utilized in selection of the next generation of candidate facility layout schemes to be evaluated. This process continues until a satisfactory solution is obtained. Finally, a case study is presented to illustrate the application of the proposed approach.
