在求解模糊优化问题的最优水平截集法中，最优水平值λ＊的确定是整个问题的关键，本文综合了模糊评判和灰色评判的优点，全面考虑影响λ＊取值的灰色因素和模糊因素，提出了基于层次分析的最优水平值灰色模糊综合评判方法，进而更加圆满地解决模糊优化问题。
In the optimal level-cut method for solving fuzzy optimization problems, the determination of the optimal level λ * is the key point of the whole problem. In this paper, the advantages of fuzzy evaluation and gray judgment are integrated, and the gray factors affecting the value of λ * and Fuzzy factors, a gray level fuzzy comprehensive evaluation method based on AHP is proposed to solve the fuzzy optimization problem more satisfactorily.
