This paper develops a robust optimization approach for a dynamic cellular manufacturing system (DCMS)integrated with production planning under uncertainty of parts processing time. To deal with thisuncertainty, a robust optimization as a tractable approach is adopted. The model includes cell formation,inter-cell layout and production planning concepts under a dynamic environment. The aim of the model is to minimize inter and intra-cell material handling, inventory holding, back order and reconfiguration costs. To verify the behavior of the presented model and the performance of the developed approach, anumerical example solved in finding an optimal solution.
