This report documents and presents the results of a study of inventory management for bus and rail public transit systems. A national mail survey was conducted of transit properties. Analysis was then conducted of the relative merits of the full range of organizational structures, policies, and practices used for inventory management. Indices useful for inventory management were then developed and defined. These indices include stockouts, turnover ratios, inventory cost per vehicle, demand satisfaction, number of stock-keeping units, shrinkage, and carrying costs based on such qualifying factors as scale, fleet size and standardization, fleet composition, mileage, etc. Significant relationships between performance indices and organizational profiles were also identified. The primary product of this study is a readily usable reference guide to assist transit professionals in better understanding, evaluating, and managing inventory. This Inventory Management Handbook summarizes inventory control techniques appropriate to the transit industry, decision-making techniques, and benchmark references. |
