在阐述集成产品开发（IPD）任务特点的基础上，研究了集成产品开发任务的耦合性和层次性，建立了分层分布式规划的策略，并引入代价矩阵概念，给出了任务调度模型和相应的匈牙利算法，并用实例演示了计算过程。

This paper is related to task arrangement of the IPD process plan. The IPD task feature is discussed in regard to coupling and administrative levels. The stratified and distributing IPD process plan strategy is built. The task arrangement modeling and related Hungary algorithms is given with conception of cost matrix, and then related examples are demonstrated.
