基于模糊判决原理，兼顾模糊目标和模糊约束的最优性隶属程度，构造判决函数；
Based on the fuzzy decision prin-cipsel, the optimal membership degrees of the fuzzy objectives and constraints are considered, and then the decision function is constructed.
灰色聚类法，不仅能够相当正确地判别结构的可靠性等级，而且在灰色聚类系数矩阵中显示了各样本对于不同鉴定等级的隶属程度。
This method can not only exactly judge the reliability grade of the structure, but also display the subjection of various samples to different grades in grey clustering coefficient matrix.
通过对各目标实现程度的隶属函数进行定义，将多目标优化问题转变成模糊规划问题进行求解。
By defining the membership function of the realization extent of each objective, the multi-objective optimization problem has been turned into a fuzzy programming problem to be solved.
