可变模糊工程综合评定方法及其应用

可变模糊工程方法可科学地确定样本指标对各级指标标准区间的相对隶属度,并且能够通过变化模型及其参数,合理地确定出样本的评价等级,提高对样本等级评价的可靠度.将该方法应用到宇航高压容器强度性能的综合评定中,评定结果与专家评定的结果吻合.可变模糊工程综合评定模型及其方法亦可应用到其它行业产品的质量评定中.同时指出可拓综合评定方法因存在的关联函数公式错误,不能用于宇航高压容器强度性能的综合评定.

Variable fuzzy engineering method of comprehensive evaluation and its application

Variable fuzzy engineering method can scientifically determine the relative membership degrees of disquisitive indexes at level intervals,and reasonably determine the evaluation level of each sample by varying the model and its parameters.The method is applied to comprehensive evaluating the intensity performance of the high pressure vessel of spacecrafts,and the evaluation result is consistent with that of experts.The variable fuzzy engineering method can also be applied to evaluating products quality of other industries.At the same time,it's pointed out that the method of the extension multi-factor evaluation can not be applied to evaluating the intensity performance of the high pressure vessel of spacecrafts for the mistakes of its basic dependent function formula.
