考虑工序间环境相关性的网络计划方法研究

传统的CPM／PERT网络计划方法都是建立在工序的参数相互独立的假定基础之上，没有考虑工序间因为环境因素而产生的关联性。为此，通过对工序间因环境因素而产生的关联性进行分析，建立了基于环境影响因素的网络计划模型，并用VC 语言编制程序实现了模型的模拟计算，最后将该模型应用到一个工程实例中，并将计算结果与传统的CPM／PERT法、一般Monte Carlo模拟法作了对比，证实了模型的可行性和有效性。

Study on network planning technique considering activities circumstance-based factors'''' correlation

The traditional CPM/PERT network planning techniques are developed on the assumption that activities' parameters are separately independent, which neglects the correlation among activities because of the circumstance factors. A circumstance_based factor model is presented, in which the correlations of activities based on the circumstance factors are analyzed, and simulation program has been developed with Visual C++. At last, the model is applied to a project instance, and the calculated result is compared with the results which are gained respectively by CPM/PERT and Monte Carlo simulation technique, which verifies the feasibility and validity of the model.
