This paper describes a computarized model that was developed to support a general modeling approach for the determination of feasible strategies for the repair/replacement of a population of units. "A Dynamic Repair/Replace Population Model" (DRRPM), is a software prototype that is capable of analyzing 12 primary streams or "groupings" a similar items with 2 operating environments per stream for a maximum planning horizon of 12 periods. Stream "groupings" are based on similar failure distributions, number of operational hours, similar operating environments etc. A simple case study is included to demonstrate the usage of the computer model. The DRRPM management and cost summaries can assist in the determinaton of appropriate maintenance programs and can facilitate systematic resource allocation for a population of repairable or replaceable units.
