STOCK LEVEL DETERMINATION AND SENSITIVITY ANALYSIS IN REPAIR REWORK OPERATIONS/

In this article, we present the results of a study examining the behav ior of various inventory stocking methodologies in repair/rework opera tions. A major area of focus is on the sensitivity of key model parame ters to stochastic replenishment lead times, product demand, and overh aul factors. A case study in a US Army depot provides validation for t he effort. Simulation results indicate the current depot stocking meth odologies are adequate in ideal conditions, but are less effective in more challenging and realistic scenarios. Results also indicate that s ame commonly used inventory models are quite robust to stochastic oper ating parameters in the unique/rework environment.
