An Assessment of the Dyna-Metric Inventory Model during Initial Provisioning.
Abstract
A goal of initial provisioning is to provide the highest level of readiness for a fixed level of investment. MOD-METRIC and AFLCR 57-27, the traditional initial provisioning methods, determine which spare parts are needed and in what quantity without considering aircraft readiness. On the other hand, Dyna-METRIC, an availability model, quantifies the number of spares needed and finds the optimal mix for a dynamic initial provisioning environment. This thesis is a comparison of the requirements computation (stock level) recommended by each method and a comparison of the aircraft availability that resulted from those stock levels. The data consists of 41 fuel system Line Replaceable Units modeled during the initial provisioning of the F-15 aircraft in FY 73 and FY74. Results indicate that the Dyna-METRIC performed equal to or better than the traditional methods for computing initial spare requirements given the same investment constraint. Further, the research suggests that the Dyna-METRIC model would recommend a smaller inventory of spare parts than the MOD-METRIC model while maintaining an equal level of performance.
