摘要
首先把工程规划中有向网络转换成带时间状态的Petri网,利用Petri网的分析方法对其不合理之处加以剖析,修正其中可能蕴含的错误,接着运行该网络并进行剪枝优化,自动获取关键路径。该方法比传统算法的执行效率要高,更易于实现。
Using extended time Petri net,the directional network of project planning was converted into its Petri net model.Any potential limitations were analyzed by the methods of Petri net and corrected firstly.The critical path of net was automatically got after operating network for pruning optimization.This algorithm has better effectiveness than the existing methods,and is easy to realize.
