Two Constrained Inventory Models

ISBN:
Category :
Languages : en
Pages : 55

Book Description
The paper presents two types of n product constrained inventory models, one lot-size and the other order-level. The constraints which are imposed on these models limit the amount of space occupied by the products at any time. Solutions are obtained for the lot-size systems which have two, three, and n products. The lot-size model is contained in chapter 3. A solution is obtained in the two product case for the order-level system. The problems involved in determining an n product solution for this system are discussed. Chapter 4 contains the consideration of this model. Chapter 5 concludes this paper with a summary of the results of the research and recommendations for future research in the area of constrained inventory systems. (Author).

Book Description
This paper presents two types of multi-item deterministic constrained inventory models which relate to the constraints of the equivalent of a direct support unit in the Federal German Army; namely, that there is only a limited amount of space available for storage of items. One is a continuous review model with no stockouts allowed and the other is a periodic review model where backorders are allowed. In contrast to previous models analyzed by Naddor and others, time phasing of the arrivals of orders of different items is allowed. The benefit derived from this phasing is the reduction in the average amounts of on-hand inventory and backorders. Solutions are obtained for the two-item case and the n-item case is discussed. Examples illustrate the results. (Author).

Book Description
The main aim of the present book is to suggest some improved estimators using auxiliary and attribute information in case of simple random sampling and stratified random sampling and some inventory models related to capacity constraints. This volume is a collection of five papers, written by six co-authors (listed in the order of the papers): Dr. Rajesh Singh, Dr. Sachin Malik, Dr. Florentin Smarandache, Dr. Neeraj Kumar, Mr. Sanjey Kumar & Pallavi Agarwal. In the first chapter authors suggest an estimator using two auxiliary variables in stratified random sampling for estimating population mean. In second chapter they proposed a family of estimators for estimating population means using known value of some population parameters. In Chapter third an almost unbiased estimator using known value of some population parameter(s) with known population proportion of an auxiliary variable has been used. In Chapter four the authors investigates a fuzzy economic order quantity model for two storage facility. The demand, holding cost, ordering cost, storage capacity of the own - warehouse are taken as trapezoidal fuzzy numbers. In Chapter five a two-warehouse inventory model deals with deteriorating items, with stock dependent demand rate and model affected by inflation under the pattern of time value of money over a finite planning horizon. Shortages are allowed and partially backordered depending on the waiting time for the next replenishment. The purpose of this model is to minimize the total inventory cost by using the genetic algorithm. This book will be helpful for the researchers and students who are working in the field of sampling techniques and inventory control.

Service Level Constrained Inventory Systems

Book Description
Motivated by the importance of service quality in nowadays customer business environment, we focus on inventory optimization under probabilistic service level constraints, namely, the alpha service level (also known as the ready rate) or the beta service level (also known as the fill rate). Under service level constraints, we consider two canonical stochastic inventory models: (i) the classical inventory control model with backlogging and (ii) the remanufacturing inventory control model with random product returns. The random demands could be nonstationary, evolving and correlated over time. For each model, we first establish the optimality of generalized base-stock policies, and then propose a new approximation algorithm that admits a worst-case performance guarantee of 2. The core concept developed in this paper is called the delayed forced holding and production cost, which is proven effective in dealing with service level constrained inventory systems. We also provide an efficient heuristic algorithm for the multi-item inventory system. Our extensive computational experiments show that the proposed algorithms perform within 2% of optimality.

Book Description
Chapter one deals with the general concepts involved in this work, scope and limitations, technique used to solve the problem with mathematical tools. Chapter two defines inventory problems, birth of inventory and various inventory models. Chapter three investigate a two stage partial trade credit policy with deteriorating items, where we determined the optimal cycle time. In chapter four two opportunity of permissible delay in payments with incremental and cash discount scheme are discussed in two sections respectively. Chapter five examines two stage credit policies with imperfect items where the determination of optimal ordering policies for retailer is prepared. Two stages of economic production quantity model with limited storage space are analyzed algebraically in chapter Six. In chapter seven two cases of variation in production corresponding to variation in demand and variation in production with variation in demand are discussed. Chapter eight deal with optimal ordering policies for retailers with different types of demand under progressive payment scheme.
