SEDS SYSTEM EFFECTIVENESS DATA SYSTEM
Abstract
This report represents the System Effectiveness Data System (SEDS) effort and was conducted at Edwards AFB on the IBM 7044/7094 computer. F-111A category II operating and maintenance data was stored on tapes using the IBM formatted File System (FFS-V8). Problems were defined by the F-111 System Project Office (SPO) and the Sacramento Air Materiel Area. These problems were associated with the eleven most critical line replaceable units (LRUs) in the F-111. The problems were: (1) Distribution of total maintenance for each LRU; (2) Relationships between LRU replacement and failures; (3) Replacement estimate for each mission type; (4) Estimate for replacements per 100 flying hours for each LRU. Solutions were provided for problems: (1) for both flight line and shop activities where the event was defined as all activity associated with the total system. Problems (2) and (3) were solved as planned. Problem (4) was solved as planned with the additional result of the probability distribution associated with each LRU replacement requirement. Hence, the risk associated with a given replacement value is quantitatively indicated. This study demonstrated that storage and retrieval of a large volume of operating and maintenance data on a timely basis appears feasible.
