Costs of the Next Due Base-Level Inspection During a Depot Visit
An outline and illustration of a method for estimating the incremental man-hour costs of doing a base-level inspection during a depot visit as a means to reduce total system costs (base and depot). It is expected that the depot can perform the base-level inspection more economically because the depot performs most of the base-level inspection in conjunction with any Programmed Depot Maintenance (PDM) and Modifications (MOD), and only a small incremental cost would be required to do the few additional tasks needed. This report discusses a simple insight based on depot maintenance procedures which reduces the forecast of the unpredictable workload to a minor problem; the predictable work can be obtained from DART (Daily Automatic Rescheduling Technique). Given an adequate sample of histories to acquire the predictable and unpredictable estimates, the results from the method described are judged to be adequate for decisionmaking. This method, illustrated in this report for the F-4 case, is believed to be applicable to other weapon systems undergoing PDM/MODs at other Air Logistics Centers.
