Decisions on material handling and machine loading in a serial production system with multiple machine cells and heterogeneous but functionally similar machines within each cell are much more complex. To facilitate material transfer, material handling systems are normally used to link the machines or cells. Furthermore, to improve production, batch jobs are usually split into sublots for handling between machines. Thus, coordinating the movement of the sublots and the assignment of the sublots to machines within a cell is a critical decision factor which, if poorly made, can significantly affect the production efficiency of the shop in terms of batch completion times. In this paper, a mixed integer programming model is formulated to plan unit load movement in a serial production system that uses mobile transporters for material handling. The model assigns unit loads to machines, determines processing and move times for unit loads, and assigns unit load movement to material handling equipment such that the total manufacturing time for the batch is minimized. Through the integrated model, a realistic and effective manufacturing plan can be obtained.
