本文提出用模糊线性规划求解网络计划最低费用日程的优化方法。过去沿用线性规划求解网络计划最低费用日程均未考虑工序弹性约束的情况,因而其解具有一定的局限性。但在实际工作中,具有弹性的工序是普遍存在的。因此,采用模糊线线性规划求解此类问題很有必要,它比过去沿用的方法更具有普遍性、实用性。
In this paper, we propose a fuzzy linear programming to solve the network planning minimum cost optimization method. In the past, the minimum cost schedule for solving network planning using linear programming did not consider the process of elastic constraint, so its solution has some limitations. However, in practice, flexible processes are ubiquitous. Therefore, it is necessary to solve such problems with fuzzy linear programming, which is more universal and practical than the methods used in the past.
