Inventory Decision Model of Single-echelon and Two-indenture Repairable Spares

摘要：

　　According to the three conditions that the variance-to-mean ratio of the spares demand is larger than,equal to or less than 1,put forward the three demand distributions such as the Negative binomial distribution,Poisson distribution and Binomial distribution.For the problem that the two-level materials demand follows the Poisson distribution,use the Negative binomial distribution to improve the forecast accuracy.In the given total security funds as constraint conditions,through total shortfall minimum instead of supply availability maximum to simplify the objective function,establish the spares inventory decision model,and optimized by the marginal analysis and compile algorithm.The example proves that the model has good accuracy and practicality.
