Various Statistical Measures of a Parallel Redundant Complex System with Two Types of Failure

In this paper we analyze a Markov model consisting oftwo non-identical units in parallel redundancy. Systemsuffers failure in two models; viz., normal mode(N.M) and common case (C.C). The repair, whereverundertaken follows general distribution. After thefailure of one of the two units, the failure rate ofanother unit is assumed to be increased as compared tothe situation on while it works jointly. This is termedas over loading effect.
