Study on Large-scale Project Network Planning in Fuzzy Environment

基于模糊网络时间参数的加法迭代计算定义 ,本文给出了计算模糊网络时间最迟时间和时差参数的分层线形规划方法。与现有文献方法相比 ,本文方法拓展了传统的网络关键路线法 ,大大减少了大型模糊网络时间参数计算的复杂性 ;并能得到有意义的网络时间参数和零时差关键工序。

Based on addition formulas for calculating time parameters in fuzzy network,this paper gives the hierarchical linear programming method for the lastest time and slack of the activities and events in the fuzzy networks. Compared with the well-known fuzzy network techniques in literature,we have generalized the classical critical path method,and simplified the fuzzy time parameters calculation in large-scale network. We can obtain not only meaningful results,but also critical activities and events with zero slack by use of the method.
