Simulation Model for Air Launched Cruise Missile Engine Management

摘要

This paper examines the management of spares acquisition and logistics support activities for the Air Launched Cruise Missile (ALCM) engine. A SIMSCRIPT II.5 simulation model of the ALCM system is developed and the probable ranges of five relevant factors (transportation time, maintenance duration, engine failure rate, test duration and test loss rate) are determined. The model is manipulated using a factorial design with the five factors at the extremes of their ranges. An ANOVA is used to determine if changes in these of the ALCM engine. This capability is expressed as the average number of days an engine must be used as an operational asset past the manufacturer's warranty period without an overhaul. The ANOVA indicated that changes in transportation time and maintenance duration had a significant effect on the operational capability of the ALCM engine and thus required further investigation to refine their range of values. The model is used to test the effects (on a number of variables of interest) of changes in maintenance policies and timing. The model should easily be adaptable to reflect the environment of the Ground Launched Cruise Missile and the Submarine Launched Cruise Missile Systems. It could then be used to estimate the number of spare engines required in these systems to meet various engine capability levels and other management goals.
