An Order-level Inventory Model for a Deteriorating Item with Weibull
نویسندگان
چکیده
Abstract An inventory model is developed for a deteriorating item having an instantaneous supply, a quadratic time-varying demand and shortages in inventory. A two-parameter Weibull distribution is taken to represent the time to deterioration. The model is solved analytically to obtain the optimal solution of the problem. It is then illustrated with the help of a numerical example. The sensitivity of the optimal solution towards changes in the values of different system parameters is also studied. Special features of a time-quadratic demand are discussed.

Optimal ordering quantities for substitutable deteriorating items under joint replenishment with cost of substitution
In this paper we develop an inventory model, to determine the optimal ordering quantities, for a set of two substitutable deteriorating items. In this inventory model the inventory level of both items depleted due to demands and deterioration and when an item is out of stock, its demands are partially fulfilled by the other item and all unsatisfied demand is lost. Each substituted item incurs a...
متن کاملDeveloping EOQ model with instantaneous deteriorating items for a Vendor-Managed Inventory (VMI) system
This paper studies the economic-order-quantity model (EOQ) for deteriorating items in two cases (with and without shortages) to evaluate how vendor managed inventory (VMI) affects supply chain. We consider two-level supply chain (single supplier and a single retailer) with one instantaneous deteriorating item. A numerical example and sensitivity analysis are provided to illustrate the effect of...

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 p...
متن کاملStudies on Some Inventory Model for Deteriorating Items with Weibull Replinishment and Generalised Pareto Decay Having Demands as Function of on Hand Inventory
Inventory models play an important role in determining the optimal ordering and pricing policies. Much work has been reported in literature regarding inventory models with finite or infinite replenishment. But in many practical situations the replenishment is governed by random factors like procurement, transportation, environmental condition, availability of raw material etc., Hence, it is nee...
