Grey Comprehensive Evaluation Method for Optimal Level Value in Fuzzy Optimization Problem
模糊优化问题中最优水平值的灰色综合评判方法

The fundamental method of the fuzzy optimization problem is coverting the fuzzy optimization problem into the usual optimization problem based on the optimal level cut set, then utilizing the usual optimization method to resolve it. The key of the method is how to decide the optimal level value.This paper presents the grey multi hierarchical comprehensive evaluation model of the optimal level value for fuzzy optimization problem based on the grey theory, and overcomes the shortcoming of the loss information on the usual comprehensive evaluation method. The exmple has shown that this model is rational and simple in calculation, and it is a new way to determine the optimal level value of fuzzy optimization problem.
