TL;DR: In this article, an economic order quantity inventory model is analyzed, considering that the unit cumulative holding cost has two significant components: a fixed cost which represents the cost of accommodating the item in the warehouse and a variable cost given by a potential function of the length of time over which the item is held in stock.
Abstract: In this paper, an economic order quantity inventory model is analyzed, considering that the unit cumulative holding cost has two significant components: a fixed cost which represents the cost of accommodating the item in the warehouse and a variable cost given by a potential function of the length of time over which the item is held in stock. Shortages are allowed and, during the stockout period, only a fraction of demand is partially backordered. The backordering cost includes a fixed cost and a cost linearly dependent on the length of time for which backorder exists. A solution procedure is developed for determining the optimal inventory policy. Moreover, to illustrate the effects of some parameters on the optimal policy and the minimum total inventory cost, a numerical study is developed.

TL;DR: This work studies an EOQ inventory model with demand rate and holding cost rate per unit time, both potentially dependent on the stock level, and presents the analytical formulation of the problem and the existence and uniqueness of the optimal cycle time, giving a numerical algorithm to obtain it.

Journal ArticleDOI
TL;DR: This paper presents a method to obtain the solution of the classic economic order quantity and economic production quantity models when the lot size must be an integer quantity and shows how this method is applicable to the resolution of other production-inventory models.

TL;DR: In this article, the authors developed an economic lot size inventory model where the demand rate depends on the stock level and the cumulative holding cost is non-linear on both the quantity and the time they are stored.

TL;DR: In this article, an inventory system with non-instantaneous deteriorating items is considered, where demand rate is a function of advertisement of an item and selling price, and an algorithm is designed to find the optimum solutions of the proposed model.
Abstract: This paper considers an inventory system with non-instantaneous deteriorating item in which demand rate is a function of advertisement of an item and selling price. This paper aids the retailer in maximizing the total profit by determining optimal inventory and marketing parameters. In contrast to previous inventory models, an arbitrary holding cost rate and arbitrary deterioration rate have been incorporated to provide general framework to the model. First, a mathematical model is formulated and then some useful theoretical results have been framed to characterize the optimal solutions. The necessary and sufficient conditions for the existence and uniqueness of the optimal solutions are also derived. An algorithm is designed to find the optimum solutions of the proposed model. Numerical examples are included to illustrate the algorithmic procedure and the effects of key parameters are studied to analyze the behavior of the model.
