Abstract
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.
