The underutilization of parallel machines due to their operational complexity has raised interests in developing efficient methodologies for sequencing the parallel machining operations. This chapter presents a mixed integer programming model for the problems. Both the genetic algorithms and tabu search methods are used to find an optimal solution. Testing problems are randomly generated and computational results are reported for comparison purposes. Introduction Process planning transforms design specifications into manufacturing processes and computer-aided process planning CAPP uses computers to automate the tasks of process planning. The recent introduction of parallel machines mill-turn machining centers can greatly reduce the total machining cycle time required by the conventional sequential machining centers in manufacturing a large batch of millturn parts 13 14 . In this chapter we consider the CAPP for this new machine tool. Dr. Lee s work was partially supported by the National Science Foundation NSF CAREER Award DMI9702374 . E-mail yslee@ 2001 CRC
