This paper develops a mixed-integer programming model to design the cellular manufacturing systems (CMSs) under dynamic environment. In dynamic environment, the product mix and part demand change under a multi-period planning horizon. Thus, the best designed cells for one period may not be efficient for subsequent periods and reconfiguration of cells is(More)
• Scheduling problem for multiple automated guided vehicles (AGVs) in a manufacturing system is proposed and formulated. • Propose a mathematical program to minimize the penalized earliness and tardiness. • Optimization method in two stages, namely searching the solution space and finding optimal solutions are proposed. • The performance of the proposed(More)
