FMS, which consists of machining centers (MC) and an automatic transportation system (AGV), is used in many part manufacturing factories to produce various parts with small and changeable lot sizes efficiently. In introducing FMS, it is important to design the optimum system and consider the optimum operation policy in order to yield the maximum production rate. In this paper, we study a job transportation policy in a basic loop type FMS. First, we analyze the optimum job transportation policy which yields the maximum production rate using a Markov decision process. Next, we analyze system parameters (position of MC, MC number, buffer capacity and AGV transportation speed) on the maximum production rate using an imbedded Markov model.
