摘　　要：以复杂网络理论为基础进行多任务调度网络的扩展,从新的角度和观点来研究多任务调度方法。给出多任务复杂有向网络的描述方法和相关数学模型,结合产品开发过程的拓扑结构和本身特性,提出刻画事件节点重要程度的评价模型和算法。有效地评估包括关键节点在内的不同节点的性质,构建基于节点重要度的调度算法。该项研究对产品开发过程中合理安排任务的执行顺序、实现制造资源优化配置有着重要的指导意义。Expand multi task dispatching network based on complex network theory, study the method of multi task scheduling from a new angle and point of view and put forward the description method and re- lated mathematical model of the multiple task complex directed network. Combining with the topology structure and characteristic itself of the product development process, come up with evaluation model and algorithm of importance degree of depicting events node. Evaluate effectively properties of different nodes, including key nodes, and construct scheduling algorithm based on the node importance degree. This study has important guiding significance for complex product development process to arrange the ex- ecution order of tasks and to implement manufacturing resources optimization confizuration.
