Stock List Provisioning Procedure with Detailed AN/SPS-40 Radar Application

摘要

During the performance of equipment evaluation by the Electronics Maintenance Engineering Center, it was found that a major source of difficulties resulted from inadequate logistic support. This logistic problem was found to be acute on the AN/SPS-40 Radar System. Because of this situation Vitro undertook a logistics study for the Navy under the direction of the Electronics Maintenance Engineering Center. This report presents the results of the logistics study to determine the procedures required to establish a spare parts provisioning list and to develop a computer program for performing the necessary associated calculations. The methods applied are probabilistic in nature involving the determination of the support necessary to meet a provisioning level. The provisioning level is defined as the likelihood that an equipment or system will be able to operate for a given period of time without experiencing a stock out or shortage of spare parts. The criterion followed in determining the sequence in which parts are considered for sparing is to progressively select the part which indicates the highest likelihood of requiring replacement. When sufficient parts have been added to accumulate the desired level, the calculation is complete.
