摘要: 基于面向对象技术,通过将PERT网络计划抽象为计划类、工作类、虚工作类和工作关系类,建立系统的类模型,然后通过构造类对象来设计系统的结构模型。根据无环路有向图理论,提出网络计划系统的工作自动排序和回路检查算法,运用数学规划的相关理论,实现系统的工期优化。经对系统的程序设计应用证明,系统能有效帮助企业快速制定网络计划,并能对其进行优化。

Abstract: Based on object-oriented technology, the PERT-type project's class model is setup by it's class project, class activity, class dummy activity and class logical relationship, and the framework model is built by constructing class objects. The algorithms of process-auto-arranging and loop-checking is also discusssed in terms of the loop-free digraph. Further, by mathematical programming, the optimization of time is achieved. Recently, the system has been applied and it's result has been proved effective to help an enterprise developing and optimizing the network plan.
