Abstract:
On the basis of analysis of lots of inventory information, an inventory control strategy is presented based on Weibull distribution. It mainly includes the definition of inventory rate and mathematical model of η(t). The distribution of η(t) accords with the weibull distribution consistency, and its physical significance is in accord with actual inventory; meanwhile, the task and task section H(t) are defined. Using H(t) as restrictive condition, some strategies of control inventory rate η(t) are gained: spare parts ordering should be done before and close to the executing of task, the closer the better, in order to control η(t) distribution rising faster. These strategies are ive proved to be effective by experimental application. These strategies can provide scientific basis for inventory control decision-making and result in a lowest inventory rate according to the above-mentioned theory.
