Essentiality Weighting Models for Wholesale Level Inventory Management
Abstract
Item essentially is currently determined in the U.S. Navy using an integer valued Item Mission Essentially Code (IMEC). Unfortunately, this ordinal coding scheme does not provide a means of determining how much more important an item with, say, an IMEC value of 4 is over an item with an IMEC value of 1. In addition, the Navy's wholesale level inventory models have no way of using these code values in determining spare and repair part inventory levels. An essentiality parameter E does exist in these models but the Navy has not developed a way to convert IMEC values into E values. This thesis proposes four models for providing this conversion. These models incorporate ideas obtained from interviews with inventory management personnel at the Navy's Inventory Control Points. Implementing one of these models in conjunction with the other recommendations presented in this thesis would result in stocking policies which better relate to the operational effectiveness for items stocked by the Navy's wholesale supply system.
