Order Level Inventory Models for Deteriorating Seasonable/Fashionable Products with Time Dependent Demand and Shortages
نویسندگان
چکیده
An order level inventory model for seasonable/fashionable products subject to a period of increasing demand followed by a period of level demand and then by a period of decreasing demand rate three branches ramp type demand rate is considered. The unsatisfied demand is partially backlogged with a time dependent backlogging rate. In addition, the product deteriorates with a time dependent, namely, Weibull, deterioration rate. The model is studied under the following different replenishment policies: a starting with no shortages and b starting with shortages. The optimal replenishment policy for themodel is derived for both the abovementioned policies.

Economic Order Quantity for Deteriorating Items with Non Decreasing Demand and Shortages Under Inflation and Time Discounting
Some products like green vegetables, volatile liquids and others deteriorate continuously due to evaporation, spoilage etc. In this study, an inventory model is developed for deteriorating items with linearly time dependent demand rate under inflation and time discounting over a finite planning horizon. Shortages are allowed and linearly time dependent. Mathematical model is presented for the p...
متن کاملPurchasing Inventory Models for Deteriorating Items with Linear Demand and Shortages - in Third Order Equation
In this paper, an purchasing inventory model for deteriorating items is developed with a linear, positive trend in demand, allowing inventory shortages and backlogging. It is assumed that the goods in the inventory deteriorate over time at a constant rate . Two models are developed for two operational policies. The first policy covers the case that the inventory model with linear demand for det...
متن کاملA New Inventory Model for Deteriorating Items with Price-dependent Demand, Time-value of money, and Shortages
This paper presents a discounted cash-flow approach to an inventory model for deteriorating items with the two-parameter Weibull distribution. According to our proposed model, two shortages are considered: back-orders and lost-sales, in which the back-order rate is a varying function of the time when the shortage happens. In general, the demand rate is a linear function of the selling price...

متن کاملPRODUCTION INVENTORY MODEL FOR DETERIORATING ITEMS WITH SHORTAGES AND SALVAGE VALUE UNDER REVERSE LOGISTICS
In this paper, a production inventory model is developed for the business enterprise which consists of three wings. The first wing is for manufacturing new items, the second wing is for collecting the returned items, while third wing is for remanufacturing the returned item. In this model we consider the fact that the storage item is deteriorated during storage periods and salvage value is inco...
