【摘要】 介绍了项目管理中，项目分解任务树和同级子任务间的串并关系，以及网络图中节点、枝线、流等3个构成要素。在分析任务扩展原理的基础上，定义了开发项目设计过程中网络图，扩展的下一层网络图，任务的子任务流和扩展网络图的概念。讨论了网络计划生成中，父子关系数据结构、串并行关系数据结构、网络计划的邻接表、任务扩展步骤，以及生成网络计划的递归算法。提供了采用该方法完成的项目网络计划生成实例。更多还原

【Abstract】 The tree task of project decomposition and the serial relation between peer subtasks, and the node, branch and flow in network graph is introduced. Based on the principle of, the network graph, sub-network graph, and subtask flow and extended network graph in design process of development project is defined. The data hierarchy with parent-child relation, the data structure with serial relation, adjacency list of network schedule, the process of extended task, and recursive algorithm for creating network schedule is discussed. The example for creating network schedule of project is given on.更多还原
