Uniform SAMMS (Standard Automated Materiel Management System) Inventory Management Simulation (USIMS) User's Guide

摘要

Inventory management within the Defense Logistics Agency is accomplished with the aid of the DLA Standard Automated Materiel Management System (SAMMS). The Uniform SAMMS Inventory Management Simulation (USIMS) is an operations research (OR) tool which permits evaluation of alternative inventory policies or environmental impacts on the performance of Defense Supply Centers (DSCs). USIMS uses a small sample of items in conjunction with a Monte Carlo simulation of various key SAMMS events to produce a wide range of inventory statistics on a proposed set of inventory policies. The USIMS was developed in the early 1970s. In the early 1980s, a phased approach to enhancing the USIMS package was agreed upon by the USIMS Steering Group, which consists of Headquarters and DSC OR personnel. One area of USIMS's enhancements involved improved documentation in the form of a user's guide. This guide is to provide users with theoretical background to the simulation, information necessary to run USIMS and assistance in the interpretation of its results.
