Concurrency Optimization in Product Development Process

In concurrent engineering, the overlap between the upstream product design activity and the downstream process design activity can shorten the duration of the product development process. But too much overlap may cause some unnecessary design revision workloads. Therefore, the problem of concurrency optimization between the product and process design activitiesis studied, and the mathematical model is founded. The algorithm for solving this problem is proposed,whose aim is to minimize the total costs caused by the delay of the completion time of the product developmentand the unnecessary design revision workloads.
