Two methods of determining resource requirements at an Air Force maintenance depot were developed. The first method is designed for new workloads and is based on infinite queuing theory formulas. Tables have been developed for this method. The second method is designed for workload with, at minimum, several months of historical data. An optimum fit test was designed to aid in fitting and smoothing the empirical data to the normal distribution. These data are then input to simulation model for determination of resource requirements. (86 pages)
