| 摘 要： | 提出了一种基于多领域专家知识的发动机模糊可靠性分配方法,以降低决策者主观偏好以及分配过程中模糊和不确定因素对分配结果的影响.基于对影响发动机可靠性因素的分析,建立了发动机模糊可靠性分配的数学模型,并以三角模糊数代替常规层次分析法中的标度,提出了一种模糊评判矩阵方法来确定影响可靠性因素的权重.在可靠性分配过程中,充分考虑多领域专家的意见和产品开发过程的风险性.以应用实例对提出方法的有效可行性进行了验证.

| Abstract: | A fuzzy reliability allocation method for engine was proposed based on multi-field experts' knowledge.In this method,fuzzy set theory was used to decrease subjective preferences of decision makers as well as fuzzy and uncertain factors in reliability allocation process.The mathematical model of fuzzy reliability allocation for engine was constructed based on the analysis of influential factors to engine reliability allocation.A fuzzy evaluation matrix method was proposed to determine the weights of the infl... |
