Reliability Analysis of Six Unit Bridge and Parallel Series Networks With Critical and Non-Critical Human Errors

Humans play a pivotal role in the design, development and operational phases of engineering systems. Reliability evaluation of systems without taking into consideration the human element does not provide a realistic picture. Hence, there is a definite need for incorporating the occurrence of human errors in system reliability evaluation. This paper presents reliability analysis of bridge and parallel-series networks with critical and non-critical Human errors. A newly developed approach is used to perform the system reliability analysis. The approach demonstrated in this paper, which consists of six unit bridge network, is a modified version of the block diagram approach.
