정비 데이터 기반 이항모델을 이용한 최적 교정주기 분석 기법

Abstract

The TMDE(Test, Measurement and Diagnostic Equipment) which is using in the military weapon system should perform a periodic calibration to maintain a measurement reliability during the life cycle. Organizations are faced with increasing pressures to minimize the costs while improving the reliability of test equipment. Previous studies suggest that reliability models are determined by considering sample size and characteristics of equipment. However an applying single model may not be fit well maintenance data of many kinds of TMDEs. An analysis method of optimal calibration interval based on maintenance data is discussed in this paper. This paper proposes performance of Confidence test and Goodness of fit test are the most suitable to compare the binomial model with observed data for TMDEs. The research results show that the reliabilities of various types of equipment are maintained during calibration intervals.
