An evaluation of the proposed MSRT replenishment model for wholesale consumable items

Abstract

This thesis compares the current wholesale level consumable replenishment inventor\" model, now in use at Na\7 Inventor\' Control Points (ICPs), with a proposed Mean Supply Response Time (MSRT) Model. The purpose of the MSRT model is to introduce a readiness measure into wholesale inventor\' management. The objective of the MSRT model is to determine inventor}^ depths which minimize the mean supply response time subject to not exceeding the inventor}' dollar investment provided by the LTCP model for the same items. The MSRT model uses a marginal analysis optimization procedure. A comparative analysis of the models' results indicates that the MSRT model provides consistently better supply system performance, in terms of supply material availability (SMA) and mean supply response time (in days), than the LICP model for items with a medium to low average quarterly demand. For medium to high quarterly demand items, there is no significant difference in the models' performances.
