Research on Comprehensive Evaluations of Equipment Maintainability Based on an Incomplete Judgment Matrix

摘要

Equipment maintainability is a key factor of equipment general mass properties. The practical problem of the importance of the maintainability index is difficult to evaluate. In this study the evaluation index system of equipment maintainability is described and an incomplete judgment matrix is introduced into the fuzzy comprehensive evaluation method. The significance of the index is compared and the weight of the index is calculated. A tracked fire truck is taken as an example, and the visual simulation and expert score methods are used to evaluate the index. The maintainability evaluation result of the tracked fire truck is calculated and suggests this method is effective for providing data on equipment maintainability evaluation.
