摘要

There are about 1,900 electrical measuring equipment in the aircraft assembly workshop and aircraft production line, which is directly related to the manufacturing quality of the aircraft. This paper evaluates the health status of electrical measuring equipment based on Analytical Hierarchy Process. The bottom-up health status evaluation system of electrical measuring equipment is established by selecting an appropriate number of health indicators. According to the failure mode summary of electrical measuring equipment, the evaluation indexes at all levels are determined, the health assessment and judgment matrix of electrical measuring equipment is constructed. The 1–9 scale method is used for quantitative analysis of the indexes of electrical measuring equipment. The health level of the electrical measuring equipment is divided into 5 levels, and the corresponding relationship between the score of the measuring equipment and the health status is formulated. The 0–1 method and fuzzy distribution method are used to score each quantitative index. The historical data of a company electrical measuring equipment is used for example analysis, and the example results show that the calculation results of the health status score of the general measuring equipment is 0.951. The health status of the general measuring equipment is health. The health status score of the special measurement equipment is 0.877. The health status of the aviation specific measuring equipment is available.
