摘　　要：针对复杂的并行产品开发过程存在强耦合的设计活动及活动间的资源竞争,基于设计活动重叠执行模式研究资源约束条件下的并行产品开发过程时间优化模型。分析耦合活动迭代过程中的活动、资源时间变化规律,提出资源受限的并行设计活动重叠执行模式;根据设计活动的执行次序,基于设计活动的重叠修改时间、反向修改时间构建资源冲突引起的停工时间模型,提出资源受限的并行产品开发过程时间优化模型,并通过实例验证了该时间优化模型的有效性。A time model of overlapped and resource - constrained product development was presented for strong coupled activity and resources competition in complex concurrent product development process. According to analysis for the change law of activity time and resource time in iteration process of coupled activities, an overlapping for concurrent design with resource constraints was proposed. Then down time model was constructed based on overlapped rework time and inverse rework time. A time optimization model of product development with resource constraints was formulated. The results of an application example show that the time model is effective.
