摘要

为了解决在产品研发阶段可靠性数据缺乏和可靠性影响因素不确定的问题,提出了一种基于灰色系统理论的可靠性分配模型。考虑重要程度、复杂程度、技术发展水平、制造水平、工作时间和环境条件6个影响因素,结合专家经验和已知的可靠性数据,采用灰色聚类分析法和基于灰色关联度求解指标权重的改进方法评估燃料电池汽车各子系统之间的相对失效关系。根据综合灰色评估值对各子系统的可靠性进行分配。将模型分配结果和该车实际故障数据比较,验证了这种可靠性分配模型的有效性。

Abstract

In order to solve the problem of the lack of reliability data and the uncertain factors in the product development stage,a reliability allocation model based on grey system theory was proposed. Considering 6 effecting factors such as the importance,complexity, technology development level, manufacturing level, working time and environmental conditions,combining with the expert experience and known reliability data,the relative failure relationship among fuel cell vehicle subsystems was elevated using improved method of solving index weight based on grey correlation. The reliability of each subsystem was allocated according to the comprehensive grey evaluation value. Compared with the actual failure data,the validity of this model was verified.
