Some reliability measures for three component-system in the presence of CCS failures and human errors

Abstract The presence of common cause shock failures (CCSF) as well as human errors in the reliability analysis of a system is discussed. The model considers three component identical system which is affected by common cause shock failures and human errors in addition to individual failures. The emphasis is on the Markovian approach in order to derive the reliability measures like Reliability function [R(t)] and Mean time between failure [E(T)] . Also these measures are compared in the presence of CCS failures as well as human errors with that of the situation when CCS failures are affecting the system. The numerical illustration is also discussed.
