proper inventory control policy and the optimal price for the items has always been one of the main topics of scientific research and industry. on the other hand, there are many products in the market witch are classified as deteriorating items. therefore the problem of determining optimal price and optimal inventory policy for this type of items is very important. in this paper a 3 echelon sup...

Global warming and climate change become a sensitive issue worldwide, many countries try to control the CO 2 emissions by investigating in projects. This study proposes sustainable inventory model reduce carbon emission. It is generally assumed that demand increasing at starting of an level decreasing ending for particular newly launched product. In this situation, usually represented Normal di...

This study proposes an EOQ inventory mathematical model for deteriorating items with exponentially decreasing demand. In the model, the shortages are allowed and partially backordered. The backlogging rate is variable and dependent on the waiting time for the next replenishment. Further, we show that the minimized objective cost function is jointly convex and derive the optimal solution. A nume...

In this paper we shall discuss with the optimal ordering policy for two warehouse inventory model of non-instantaneous deteriorating items and stock-dependent demand. Here shortage is not allowed. Here the holding and deteriorating costs in both warehouses are different and assumed that the holding cost in the RW(rented warehouse) than in the OW(owned warehouse) the optimal solution are shown. ...

This study revisits a fuzzy rough economic order quantity (EOQ) model for deteriorating items considering quantity discount and prepayment. Since the proposedmodel is amixed integer nonlinear programming type, it is solved using Meta heuristic algorithms. Based on three different case examples, we have shown that our results using the Bees Colony Optimization (BCO) algorithm performs better tha...
