An EOQ model for items with Weibull distribution deterioration, stock-dependent demand and time-dependent partial backlogging

摘要

This paper presents an inventory model for items with Weibull distribution deterioration, stock-dependent demand and time-dependent partial backlogging. The demand rate is assumed to be a linear function of current inventory level and the deterioration rate is taken to be variable and follow a two-parameter Weibull distribution. The backlogging rate is variable and dependent on the waiting time for the next replenishment. A numerical example is presented to illustrate the application of the inventory proposed in this paper.
