Optimization of Hole-Making Operations.

This paper reports a tabu-search approach to minimize the total manual processing cost for hole-marking operations. on Power Press. Four issues, namely, Manual marking on angle, ideal time of machine while marking, non operating cycle time increase, and tang of production not match with mass production tang. The total processing cost consists of Ideal machining time cost, operates ideal time cost. In addition the problem under consideration is more complex since the cost associated with each operation is both sequence-dependent and position-dependent. To provide an efficient solution procedure, a tabu search approach is used. To improve the search performance two new neighborhood generation and move selection policies have been proposed and tested. The decisions on the above issues can be made simultaneously based on the output of the proposed algorithm. The results obtained from computational experiments show that the total processing cost can be significantly reduced within a reasonable time.
