한국 표준형 무인자동운전 고무차륜 경량전철 시스템 신뢰성 평가

초록

Reliability is defined to be the probability that a component or system will perform a required function for a given period of time when used under stated operating conditions. It is the probability of a nonfailure over time. Korea Railroad Research Institute developed the Driverless Rubber Tired Korea-AGT from 1994 to 2004. K-AGT System is Driverless and complex system to be consist of many components. Therefore, it is necessary to perform a Reliability estimation. So, we have performed reliability estimation from 2005 in the test line. In this paper, Divided a Reliability estimation period in two parts and compared MKBF of Part 1(from 2005 to 2007) with MKBF of Part 2(in 2008). Finally, The MKBF of K-AGT System has been improved through the failure analysis and redesign
