产品开发过程管理中协调组件研究

Research on coordination component of management in product development process

针对目前产品开发过程中时间上相互关联任务之间缺乏有效调度和管理的现状,介绍了时间上相互关联的任务之间的关系;以广义模糊时间Petri网为理论基础,根据关联任务之间不同的关系,建立了相应的协调机制,并引入组件理论,在工作流的系统中构建了协调组件,减少了并行和串行环节的等待时间,提高了工作效率,而且从一定程度上降低了系统的死锁概率,为实际系统进行模拟、性能评价和优化提供了强有力的支持.

In view of the lack of efficient coordination and management between temporal interdependent tasks in the product development process, the relations among the temporal interdependent tasks are introduced. On the basis of generalized fuzzy timed Petri nets, coordination mechanism and coordination components are established to coordinate interdependent tasks according to the different relationships between them. The waiting time of key step of parallel and serial executive tasks is shortened, the efficiency is improved, and the probability of deadlock of relative process can be reduced to some extent. The proposed coordination component offers strong support to simulate, evaluate and optimize the performance of the system models.
