In this paper an inventory system for continuous decaying items with stochastic lead time and Poisson demand is assumed. Since the products are deteriorating and demand is stochastic it is possible to deliver less than customers' demand to them. Thus, a c... see more

The paper studies an inventory model for deteriorating items when demand for the item is dependent on the selling price. Shortages are allowed and backlogged, and price inflation is taken into consideration. Further, it is assumed that the supplier permit... see more

The economic production quantity (EPQ) model is widely employed in reality and is also being intensively developed in the research area. This research tries to develop more realistic EPQ models for deteriorating items by considering stochastic machine una... see more

Many researchers have developed two echelons supply chain, however only few of them consider deteriorating items and unreliable machine in their models In this paper, we develop an inventory deteriorating model for two echelons supply chain with unreliabl... see more

In this paper, we propose an appropriate inventory model for a non-instantaneous deteriorating items having Ramp-type demand rate with time dependent deterioration rate. In this model, the shortages are allowed and, which is partially backlogged. The back... see more

In this paper we discuss the development of an inventory model for deteriorating items which investigates an instantaneous replenishment model for the items under cost minimization. A time varying type of demand rate with infinite time horizon, exponentia... see more

This paper develops an inventory model for deteriorating items consisting the ordering cost, unit cost, opportunity cost, deterioration cost and shortage cost. In this inventory model instead of linear demand function nonlinear exponential function of tim... see more

The aim of this paper is to develop an optimal replenishment policy for inventory models of deteriorating items with ramp type demand under permissible delay in payments. Deterioration of items begins on their arrival in stock.  An example is also pr... see more

Inventory models for a policy of retail pricing and perishable items have been developed in many papers, but very few of the studies incorporate both of these effects. This study integrates the two conditions from a three-echelon supplier’s chain and offe... see more
