Describes MANPOWER, a computer model for predicting the total force base-level maintenance personnel requirements of prospective aircraft in the USAF Tactical Air Command. The model is designed to be used early in the acquisition process when it is desirable to understand the probable total maintenance personnel requirements of proposed weapon systems. MANPOWER requires inputs concerning mission types, sortie rates, sortie lengths, deployment patterns, squadron size, peacetime base sizes, and maintenance workload. The workload can be expressed as maintenance manhours per flying hour or, if more information is available, in terms of mean-time-between-failures and mean-time-to-repair at the second digit work unit code level. Model output includes estimates of personnel requirements for the total force, for individual base size/deployment patterns, for maintenance squadrons, for officers and enlisted personnel, for overhead and supervision, and for major individual shops and groups of work centers.
