An effective inventory management control strategy

Abstract

An inventory strategy for spare parts of equipment maintenance is proposed. Its main content includes defining for inventory rate η, extracting mathematic model of η(t), and getting the result that the distribution rule of η(t) accords with Weibull distribution. Further more, this paper defines task and task time section H(t), and regards them as constraint to get some strategies. To control the climbing edge of model curve to ascend rapidly, we try to shorten the time of ordering spare parts, equal important, to control the falling edge to descend rapidly, try to reduce the time of carrying out task. The experiment shows the strategies are effective. It can provide science foundation for spare parts inventory, and make inventory rate to reach minimum format. © 2012 Springer-Verlag GmbH.
