Abstract—In this paper, Economic Order Quantity (EOQ) based model for non-instantaneous Weibull distribution deteriorating items with power demand pattern is presented. In this model, the holding cost per unit of the item per unit time is assumed to be an increasing linear function of time spent in storage. Here the retailer is allowed a trade-credit offer by the supplier to buy more items. Als...

This paper deals with an economic order quantity model where demand is stock dependent. Items received are not of perfect quality and each lot received contains percentage defective imperfect quality items, which follow a probability distribution. Two cases are considered. 1) Imperfect quality items are held in stock and sold in a single batch after a 100 percent screening process. 2) A hundred...

This paper deals with an economic production quantity (EPQ)model for deteriorating items with price and advertisement dependent demand. We have considered three types of continuous probabilistic deterioration functions to determine the total inventory cost. Here, the rate of replenishment is considered to be a variable and the generalized unit production cost function is formulated by incorpora...

We consider a continuous-review inventory system in which the setup cost of each order is a general function of the order quantity and the demand process is modeled as a Brownian motion with a positive drift. Assuming the holding and shortage cost to be a convex function of the inventory level, we obtain the optimal ordering policy that minimizes the long-run average cost by a lower bound appro...

A deteriorating inventory model using time-value of money with price dependent declined quadratic demand allowing promotion policy is developed for a deterministic inventory system. This study applied the discounted cash flows (DCF) approach for problem analysis with shortages in economic production quantity (EPQ) model. The objective of this model is to maximize the net present value profit so...

In the newsvendor game, the expected-profit-maximizing order quantity is higher in the demand interval when the per-unit profit margin is high, and lower in the demand interval when the per-unit profit margin is low. However, laboratory experiments show a “pull-tocenter” effect: average order quantities are too low when they should be high and vice versa (Schweitzer and Cachon, 2000). We replic...

This paper presents the possible effects of a temporary price discount offered by a supplier on a retailer’s replenishment policy for deteriorating items with linear time dependent demand rate. The optimal ordered quantity of a special order policy for a selected case is obtained by maximizing the total cost saving between special and regular orders for the duration of the depletion time. An al...

It is well-known that the production-inventory problem for deteriorating items in supply chain a challenge when deciding on how many products to manufacture obtain maximum total profit. This research work develops an economic production quantity model item under partial trade credit policy considering inflation, effect of reliability factor system, and demand depending price product whose selli...

In the classical newsboy problem, no cost is assumed if the ordered quantity is less than the demand. However, in reality failure to meet demand is always associated with a penalty. The aim of this work is to extend the analysis of the distribution-free newsboy problem to the case when shortage cost is taken into consideration. The analysis is based on the assumption that only the mean and vari...
