Stochastic Inventory Control Model with Manufacturing and Remanufacturing Hybrid System

摘要

In recent decades,for the pressure of the environmental legislations,the economical interesting and the conscious of environment,many producers have to take their products back after used.The product tack back (PTB) program would bring economic burden to the producers,while many of the returned products have economic value and could be remanufactured to satisfy the market demand.Inventory management is an essential area in the remanufacturing process.In this paper,we extend the traditional EOQ model to a stochastic EOQ inventory model for product remanufacture.We assume that the return is an independent Poisson process and derive the exact expression of expected average total cost under this strategy.By means of numerical simulation,we find the optimal control parameter under different situation and investigate the effects of different cost parameters on costs.
