Optimal Inventory Control Based on Accumulating Lot-Sizing Disposal Model in Reverse Logistics

Driven by growing environmental concerns, legislative actions and economic profit, manufacturers concern more and more about the inventory control of the reverse logistics, which is one of the most important research fields. Accumulating lot-sizing disposal model is developed for optimal inventory control of reverse logistics, on the assumption that the product return is permitted, Poisson distribution is obeyed and the recovered products can be sold as "new". A simple method is presented for determining the optimal order quantity and accumulating lot-sizing for returns. Applied examples are also shown. The issues for future research on the reverse logistics system are proposed
