A multivariant exponential shared-load model

A shared-load model of the exponential distribution is used to describe the characteristics of dependent redundancies. In the shared-load model, the redundant components equally share the workload. Upon failure of one or more components, the remaining components must carry an increased load. This study extends the Freund bivariate model to a three-component model and a special N-component model. A general form for system reliability is developed. Failure rates are estimated using maximum likelihood. Systems such as a multiprocessor computer, a multiple-engine system, and a paired system can be described by this model.<
