Approximations to Moments of Parallel-System Lifetime based on Sampling from a Finite Population
Ravishankar K. Iyer · IEEE Transactions on Reliability · 1979
This paper describes a procedure for generating approximate expressions for the first and second moments of system lifetime. The technique is based on the principles of sampling from a finite population. In addition a method is given for employing these expressions in system optimization, which results in a considerable decrease in the dimensionality of the problem.
