A Retail Level Inventory Model for Naval Aviation Repairable Items.

Abstract

The inventory model used by the U.S. Navy for aviation repairable items was analyzed and found to be deficient in two major areas. The method in which input data is used is found to be overly conservative. The underlying theoretical model was identified as an M/M/oo queueing model. The assumption of unlimited repair capacity in this model is not valid for application to Navy maintenance activities. An alternate inventory model is developed which substantially improves on these deficiencies. The proposed model theorizes two parallel repair processes differentiated by the existence or absence of awaiting parts time. Each of the repair processes is modelled with an M/M/1 queueing model. Simulation with data obtained from the USS RANGER 1983 deployment supports the contention that the proposed model does a superior job of estimating inventory requirements. (Author)
