针对并行工程设计活动的新特征和并行工程顺利进行的关键因素，提出一套适合并行工程的活动规划方法。该算法折衷考虑了活动间的时序、信息、资源等约束，能保证资源的有效利用、信息的顺利流动，以达到提高设计并行度、缩短设计总时间的目的。算例结果表明了该算法的可行性。 Aiming at the new features of concurrent engineering design activities and the key factors for the smooth progress of concurrent engineering, a set of activity planning methods suitable for concurrent engineering was proposed. The algorithm compromises the constraints of timing, information, and resources between activities and ensures the effective use of resources and the smooth flow of information to achieve the goal of improving the degree of design parallelism and shortening the total design time. The results of the example show the feasibility of the algorithm.
