摘要
并行工程环境中 ,上游产品设计活动和下游过程设计活动之间的重叠 ,可缩短产品开发过程的持续时间。但过多的重叠也会导致不必要的设计修改。为此 ,研究了产品与过程设计活动之间的并行度优化问题 ,并建立了数学模型 ,给出了求解该问题的算法 ,其目的是使因延迟产品开发完成时间和不必要的设计修改而带来的成本尽可能最低。
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.
