A deterministic inventory model with two levels of storage (own warehouse and rented warehouse) with non-instantaneous deteriorating items is studied. The supplier offers the retailer a trade credit period to settle the amount. Different scenarios based on the deterioration and the trade credit period have been considered. In this article, we have framed two models considering single warehouse ...

The proposed study considers both product deterioration and production process deterioration in a traditional Economical Production Quantity model. In this model, backlog and rework process are also taken into consideration while the production process is assumed to be imperfect. Unserviceable products will be manufactured as a result. Unserviceable products are kept in storage until the end of...

Supply chain management is concerned with the flow of material and information linking across suppliers & users. The coordination among processes plays vital role when different types of products are moving from many suppliers to number of buyers and it turns into more difficult phase when products are deteriorating in nature. Current study employs the same bases to develop a model, where deter...

While the development and application of inventory control models of deterioration products is one of the main concerns of researchers and practitioners, most studies done in this field have focused on inventory models under fixed supply lead time assumption. In this paper, at first we study researches done in inventory control of deteriorating items and classify them based on modeling approach...

In this paper, we study a monotone process maintenance model for a multistate system with k working states and failure states. By making different assumptions, we can apply the model to a multistate deteriorating system as well as to a multistate improving system. We show that the monotone process model for a multistate system is equivalent to a geometric process model for a two-state system. T...

The bullwhip effect phenomena in supply chain management were discussed a lot in the literatures. Most of them provided empirical evidences or analytical formulas to demonstrate the existence of the bullwhip effect in a simple two or more echelons supply chain. This paper will explore the phenomena in a quite different situation: a supply chain with deteriorating products. Unlike the convention...
