Abstract: Traditional verification method is not suitable for complex equipment MTTR verification. This paper presents a method of verifying the group which comprises sub-system of the complex equipments based on degree of similarity of MTTR curve. It determines similarity degree of curves by similarity, and group curves by stratified keystone grouping method. It verifies groups by traditional verification method. It presents a new method for verification of complex equipment MTTR.

Key words: MTTR curve, similarity, fuzzy similarity unit, similarity degree, grouping

摘要： 针对目前传统验证方法不适用于直接对复杂装备的MTTR验证，提出根据MTTR曲线的相似程度将装备各分系统分组、对组进行验证的方案。根据相似性原理确定各分系统MTTR曲线相似度，再用分层重点分组方法对曲线进行分组，运用传统的验证方法对各组进行验证，为复杂装备MTTR的验证提出新的思路。
