该程序能实现的功能，若活动图有回路则无法计算出关键路径，即解决了判断工程的可行性问题。通过对工程活动的输入，可以建立任意的AOE网进行判断。对于输入的网，可以计算出每个活动的最早开始时间，最迟开始时间和全工程可以完成的最早时间，并找出关键路径和关键活动。-the program can achieve the functional, if a circuit map activities can not be calculated critical path, that is a judgment to resolve the feasibility of the project. Right through the importation of construction activities, we can establish arbitrary judgment AOE network. The network for the importation can be calculated for each of the earliest start time, the latest starting time and the entire project will be completed in the first time, and identify key and critical path activities.
