Online lot-sizing problems with ordering, holding and shortage costs
نویسنده
چکیده
We study inventorymanagement problemswhere demands are revealed incrementally and procurement decisionsmust bemade before the demands are realized. There are no probabilistic distributions nor nontrivial bounds to characterize demands. We consider two cost minimization problems: (1) perishable products with lost sales and (2) durable products with backlogged demand. In both problems, costs are period dependent. These problems are analyzed by utilizing linear-fractional programming and duality theory. Structural results are proved and then developed into practical strategies. © 2011 Elsevier B.V.

Determine the Optimal Order Quantities in Lot Sizing Models Regarding Minimum Order Quantity with Simulation
Lot sizing Minimum order quantity Shortage Simulation In this study, lot sizing models of offer so that the cost shortage, holding inventory of exposure, ordering are to be considered and try to determine the values of Qm or maximum inventory so that the total cost could be as little as possible. Lot sizing systems with the specified consumption in a general model are studied and optimization o...
متن کاملOptimal lot sizing in screening processes with returnable defective items
This paper is an extension of Hsu and Hsu (Int J Ind Eng Comput 3(5):939–948, 2012) aiming to determine the optimal order quantity of product batches that contain defective items with percentage nonconforming following a known probability density function. The orders are subject to 100 % screening process at a rate higher than the demand rate. Shortage is backordered, and defective items...
متن کاملModeling and Analyzing Incremental Quantity Discounts in Transportation Costs for a Joint Economic Lot Sizing Problem
Joint economic lot sizing (JELS) addresses integrated inventory models in a supply chain. Most of the studies in this field either do not consider the role of the transportation cost in their analysis or consider transportation cost as a fixed part of the ordering costs. In this article, a model is developed to analyze an incremental quantity discount in transportation cost. Appropriate equatio...
متن کاملEconomic order quantity model for growing items with incremental quantity discounts
Certain inventory items are living organisms, for example livestock, and are therefore capable of growing during the replenishment cycle. These items often serve as various saleable food items downstream in supply chains. The purpose of this paper is to develop a lot sizing model for growing items if the supplier of the items offers incremental quantity discounts. A mathematical model is derive...
