A simple and accurate process is needed for comparing proposed equipment to existing operational equipment in order to forecast the resources required to support the proposed equipment. Maintenance manpower modeling needs such as a process to predict manpower, spares, and support equipment for newly designed weapon systems. As a first step toward developing the needed techniques for comparing old and new equipment, a systematic study was made of the present state-of-the-art. Current literature was reviewed, personnel who perform comparability analysis were interviewed, and past comparability studies were analyzed. This effort found that a distinction should be made between the broad topic of comparability studies and the specific procedures of comparability analysis. A comparability study is the overall process used to estimate resource requirements for new equipment using the procedures of comparability analysis to find operational equipment which is similar to the proposed equipment. It also was found that no standardized, reliable procedure exists for performing comparability studies including comparability analysis. It is recommended that a quantitative procedure be developed for comparing new equipment with equipment in the operational inventory. It is further recommended that a quantitative procedure be developed for computing an adjustment factor relating the operational equipment to the proposed equipment. Author
