Résumé :

The development and application of inventory models for deteriorating items is one of the main concerns of the experts in the domain, since the number and variety of deteriorating products are dramatically increasing. One of the major gaps in the deteriorating inventories literature is that researchers have not paid enough attention to two important features in their models: i) Considering stochastic conditions; especially stochastic lead time is almost overlooked since makes the mathematical challenges complicated, ii) designing innovative inventory policies by taking into account the environ

Résumé :

This thesis in the field of inventory management for deteriorating items studies the effects of deterioration on optimal policies in inventory and production-inventory models. Four different models are developed and analysed to address some of the gaps identified in this part of the inventory management literature. The first two models have been studied adopting the classic approach towards inventory modelling, where the holding cost is assumed to be proportional to a known exogenous unit holding cost parameter. Taking this approach, first a two-echelon (single-buyer, single-supplier) model is

It enables one to study inventory management problem without understanding the complicated calculus. This study discusses how the non-calculus (or without derivatives) method applies to the deteriorating inventory problems. We start by simplifying deteriorating inventory model so the decay curves are approximately a straight line. Then, we derive the EOQ and EPQ model using non-calculus method. We

The demand function presents the expression of a time and price-demand relationship by iso-elastic model and IFS(inventory followed by shortages) purchasing policy has been introducted into the thesis.

Inventory research used to consider from the perspective of the buyer, veryfew consider from the perspectives of both the buyer and the seller. Our study considers the perspectives of both the buyer and the seller as wellas the joint cost for finite replenishment model.

Résumé :

碩士<br>淡江大學<br>管理科學學系<br>87<br>Deteriorating inventory models have been widely studied in recently years, because the effect of deterioration is very important in many inventory systems. Deterioration is defined as decay or damage such that the item can not be used for its original purpose, e.g., food items, drugs and radioactive substances. In the present paper efforts have been made to analyze an EOQ model for inventory of item that deteriorates at a time-decreasing rate, assuming the shortages quantities will be partial backordered and the demand rate a ramp type function of time.

碩士<br>國立中央大學<br>工業管理研究所<br>95<br>In some retail contexts, stocking large quantities of inventory may not only improve service levels, but can also stimulate demand. Marketing researchers also recognize the demand of many retail items is proportional to the amount of inventory displayed. For products having demand rates that increase with inventory levels, we present an inventory model for deteriorating items with stock-dependent demand over a finite planning horizon. In addition, we also incorporate the effect of quantity discount and time factor of purchase cost while inventory decision makin

One of the important task of inventory management is to control the inventory quantity and determine the optimal order interval. Many researchers were devoted to the development of various inventory models. K.S.Park, however, developed the first production inventory model for deteriorationg raw materials and a single finished product. Equations for obtaining the exact average total cost function were then derived. K.S.Park couldn't prove that there is an unique optimal solut

When finite production rate, salvage value and shortage, the constant replenishment rate and varying demand rate, are considered the deterioration rate can be divided into two stages. Beginning the model, the goods won’t deteriorate in this period, but after a constant time, the goods are starting to deteriorate as a constant rate. The optimal solution procedures for the present problems are provided, and numerical examples are also followed to illustrat

碩士<br>淡江大學<br>統計學系<br>89<br>Classical inventory models developed by Harris(1915) and extended by Wilson(1934) deal with constant demand rate of the product. They assumed that products decrease just because of the demand in the market and products’ storing have no deadline. However, in daily life, the deteriorating of goods is a very common phenomenon. Pharmaceuticals, foods, vegetables and fruit are a few examples of such items. For longtime storing, they are no more fresh. The deteriorating items result in the decreasing of the products. Therefore, the loss due to deterioration cannot be negl

Beside traditional fixed production rate, production rate may change at any time in some case. For example, it may adjust by the market demand or by the inventory level. Besides, deterioration is a common phenomenon in many products. It is defined as decay or damage such that the item cannot be used for its original purpose (eg.

碩士<br>中原大學<br>工業工程學系<br>85<br>Most literature in the field of inventory management has not considered the time-value of money. This has happened partly due to the belief that the consideration of time-value has insignificant influence on the decision variables. During the last two decade, however, monetary situation of most countries has changed; this result in a sharp decline in the purchasing power of money. An inventory is usually a large portion of a firm''s asset. If it is not in storage, the asset can be invested elsewhere. Therefore, the consideration on the effect of time-value of

The rented warehouse is chose to store products if it has better facilities and/or a lower cost. An important issue in inventory management is to decide where to stock the goods; moreover, most products have a deteriorating characteristic. Recently, the two-warehouse inventory issue has received considerable attention. In this paper, we consider a single-manufacturer and single-distributor inventory model with deteriorating
