Title: Spare Part Inventory Management Model for Better Maintenance of Intelligent Transportation Systems
Accession Number: 01371100
Record Type: Component
Abstract: New Jersey’s highway transportation system is highly dependent on the performance of its roadways in order to maximize operational capability and to minimize travel time and congestion. Long-term sustainability of the highways performance is directly related to the efficiency of the Intelligent Transportation Systems (ITS) that need to be maintained and operated properly. One of the most important concerns within the inspection and maintenance procedures of ITS equipment is timely availability of the spare parts of essential components of ITS. Long-term down time of ITS equipment due to the unavailability of spare parts will not only increase personnel and repair time requirements, costs of replacement parts but also might lead to increased delays, poor air quality and fuel consumption. In this paper, we propose an “efficient spare parts inventory control model” that can determine the optimum levels of the safety stocks under probabilistic failure and availability assumptions for components of various ITS equipment. When this inventory control model is fully integrated into Rutgers Intelligent Transportation Systems Inspection and Maintenance Software (RITSIMS) (1), it will allow its users to efficiently manage DOT’s ITS spare parts inventory using historic maintenance and inspection data that is being collected by respective databases of RITSIMS. This inventory control model will also be able to account for the worst case scenarios that DOT can experience in terms of unexpectedly high level of equipment failures due to natural or other disasters such as hurricanes.
