Abstract : The Air Force Human Resources Laboratory has worked with and developed three maintenance support resource forecasting models. They are the Logistics Composite Model (LCOM), Reliability and Maintainability Model (R&M), and the Expected Values Model(EVM). The objective of this study is to analyze these three models in terms of: (a) how they relate to each other, (b) the minimal data requirements of each model, (c) how the models can best be used in the weapon system acquisition process, and (d) whether the models generate roughly equivalent results. In meeting these objectives, all three models were compared in terms of input requirements, method of processing, and output products. Volume I of this paper gives the analytic portion of the study. The results of the equivalence testing for the two average value models are included in Volume II. The second volume also contains a final section that discusses the conclusions from the study. A new average value model should be developed to work in conjunction with LCOM, incorporating the network tracing capability of the EVM and the variety of output of the R&M. This new model should include the average turn-around time computations and outputs for each flightline maintenance network. That could give design engineers an idea of the readiness capability of the weapon system early in the weapon system acquisition process. As soon as a gross level maintenance network is ready for the complete projected weapon system, then the LCOM simulation should be run to check out: (a) interaction of maintenance on resource requirements, and (b) the overall weapon system readiness capability.
