Maximum Likelihood Estimation for Availability Measures of a Three Component Identical System in the Presence of Human Errors and CCS Failures

This paper deals with the 3-co mponent identical system under the influence of hu man errors and Co mmon Cause Shock (CCS) failures. The M L estimates of system availability and frequency of failures were developed in the case of series and parallel systems. Also we developed empirical evidence to establish the valid ity of the proposed estimates by simu lation study.
