Abstract

As a case study on determining the replacement interval for the CMB contactor, we analyzed a field failure data during 59 months and through the simulation reliability is analyzed. As a result of analyzing the reliability we estimated parameters and analyzed distribution characteristics. Ultimately using the estimated results and applying the Age Replacement Policy considered the cost information, CMB contactor's replacement interval is determined. Through the comparison, analysis between the replacement interval and manufacturing company's, the necessity of replacement interval that is reflected in our operation circumstances is examined.
