JUST-IN-TIME SCHEDULING WITH TOOL REPLACEMENT CONSIDERATIONS

This paper addresses the combined JIT scheduling and tool replacement problem on a machining centre. The objective is to determine job sequence, tool spare requirement and corresponding replacement intervals so that the total expected processing cost is minimized. Due to the combinatorial nature of the problem, a tabu search approach is proposed to find good and quick solutions. An example problem is solved to illustrate the proposed procedure
