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 book presents a compilation of over 200 numerical problems and solutions that students can use to learn, practice and master the Inventory Control and Management concepts. Intended as a companion to any of the standard textbooks in Inventory Control and Management and written in simple language, it illustrates very clearly the steps students need to follow in order to solve a given problem. It also explains which solution methodologies can be used under which circumstances. Offering an ideal one-stop resource for mid-level engineering and business students who have taken Inventory Management or a related subject as an elective, this book is the only one students will ever need to prepare and gain confidence for their examinations in this subject.

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
In this paper, an inventory model is developed without shortages where the production cost is inversely related to the set up cost and production quantity.

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
This book focuses on the tactical planning level for spare parts management. It describes a series of multi-item inventory models and presents exact and heuristic optimization methods, including greedy heuristics that work well for real, life-sized problems. The intended audience consists of graduate students, starting scholars in the field of spare parts inventory control, and spare parts planning specialists in the industry. In individual chapters the authors consider topics including: a basic single-location model; single-location models with multiple machine types and/or machine groups; the multi-location model with lateral transshipments; the classical METRIC model and its generalization to multi-indenture systems; and a single-location model with an explicit modeling of the repair capacity for failed parts and the priorities that one can set there. Various chapters of the book are used in a master course at Eindhoven University of Technology and in a PhD course of the Graduate Program Operations Management and Logistics (a Dutch network that organizes PhD courses in the field of OM&L). The required pre-knowledge consists of probability theory and basic knowledge of Markov processes and queuing theory. End-of-chapter problems appear for all chapters, with some answers appearing in an appendix.
