分析了不确定性网络直接优化的现状、优化的困难、目前存在的问题 ;给出了不确定网络直接优化的原则以及一般方法 ,同时建立了 PERT网络工期压缩、最优工期的线性规划模型、灰色线性规划模型 ,改进了传统的资源优化法.

After analyzing the actuality of uncertain network's direct optimizing, difficulty of optimizing and the existing question at present, the principle and common method of uncertain network's direct optimizing was put forward, at the same time PERT network time limit for a project compression, linear programming model of the optimal time limit for a project and gray linear programming model was established, the traditional resource optimizing method was improved.
