Describes the assumptions and methodology of the improved TRACE model and also serves as a user's manual. TRACE is a one-sided expected-value model that simulates the allocation and consumption of resources from a set of airbases in a combat environment; output is in terms of targets destroyed, aircraft lost, and munitions consumed. TRACE is structured so that sortie allocation policies, munitions availability (through prepositioned stocks at the airbases or through resupply), force activity rates, weather, and weather forecasting ability are easily varied by the user. The model was developed to provide a means of relating materiel resource availability and operational capability. Current specifications allow up to 20 airbases, 25 munition types, 12 aircraft types, and 35 target types; runs of up to 90 days of simulated air operations can be made. TRACE is programmed in FORTRAN IV. 165 pp. Ref.
