Because of the desire to improve operational readiness and to simultaneously reduce support costs, there is a great deal of interest in the military services in implementing multi-echelon models for determination of adequate but economical stocking levels for spare parts. Two models presently used- -METRIC and MOD-METRIQ- -are inefficient and require excessive time for computation. In an attempt to solve these deficiencies a heuristic model was developed at the Naval Postgraduate School. The main purpose of this thesis is to compare the characteristics and performance of the simple heuristic model with the MTERIC solution. Comparisons with METRIC revealed that the heuristic model was much more efficient computationally, but the solution was frequently far inferior to that obtained by METRIC. The comparison indicate strongly that base (shipboard) stock levels as determined by existing allowance models are larger than are needed in an integrated system.
