Book Synopsis Designing a Multi-Product Multi-Echelon Inventory System by : Donald Gross
Download or read book Designing a Multi-Product Multi-Echelon Inventory System written by Donald Gross and published by . This book was released on 1979 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large scale inventory distribution systems typically require a hierarchy of retail stores and warehouses to satisfy the demands of their customers. This paper presents a 0-1 nonlinear programming model for finding the best design of such systems. To use this model, it is necessary to know the optimal inventory policies for multi-echelon system. Therefore, part of this paper is devoted to describing how a dynamic programming approach, first suggested by Andrew Clark, can be used to obtained these policies. The paper presents examples of the use of the nonlinear programming model to find the design of an inventory distribution system. Finally, we present a reformulation of the nonlinear programming model as a 0-1 linear programming model, incorporate capacity constraints at the retail stores and warehouses, and illustrate the use of the new model.

Book Synopsis Optimal Design of Multi-Product Multi-Echelon Inventory Systems by : Charles E. Pinkus
Download or read book Optimal Design of Multi-Product Multi-Echelon Inventory Systems written by Charles E. Pinkus and published by . This book was released on 1972 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large scale inventory distribution system typically comprise a hierarchy of retail stores and warehouses. The paper presents a model for finding the optimal design of such systems. Given the maximum number of facilities under consideration and their possible locations, the problem is to determine which facilities to include in the system and which products to stock at each in order to minimize the cost of the system. Demand for the products may be deterministic or stochastic. To use the model it is necessary to know the optimal inventory policies for the multi-echelon systems under consideration, however, an important feature of this work is that any multi-echelon model may be used in tandem with this design model. Included is an example to illustrate the model and the two points which are the basis for its formulation: first, there is generally no single design which is best for all products; second, the design which is optimal for a given product is not necessarily the best design to use when trying to minimize the cost of the entire system.

Book Synopsis The Design of Multi-Product Multi-Echelon Inventory Systems Using a Branch-and-Bound Algorithm by : Charles Edward Pinkus
Download or read book The Design of Multi-Product Multi-Echelon Inventory Systems Using a Branch-and-Bound Algorithm written by Charles Edward Pinkus and published by . This book was released on 1971 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large-scale distribution systems require a hierarchy of retail stores and warehouses to satisfy the demand of their customers. Given the maximum number of installations and their possible locations, the problem is to determine which installations to include in the design of the system and which products to stock at these installations. Demand for the products is assumed known and may be deterministic or stochastic. The objective is to find a solution to this design problem which minimizes the total (expected) discounted cost for the lifetime of the system. This problem has been formulated as a combinatorial optimization problem and solved by a branch-and-bound algorithm. The subproblems of the algorithm are tractable integer linear programs. Applications of this model to the design of other multi-use, multi-facility systems are briefly described. (Author).
Book Synopsis Optimal Inventory Modeling of Systems by : Craig C. Sherbrooke
Download or read book Optimal Inventory Modeling of Systems written by Craig C. Sherbrooke and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most books on inventory theory use the item approach to determine stock levels, ignoring the impact of unit cost, echelon location, and hardware indenture. Optimal Inventory Modeling of Systems is the first book to take the system approach to inventory modeling. The result has been dramatic reductions in the resources to operate many systems - fleets of aircraft, ships, telecommunications networks, electric utilities, and the space station. Although only four chapters and appendices are totally new in this edition, extensive revisions have been made in all chapters, adding numerous worked-out examples. Many new applications have been added including commercial airlines, experience gained during Desert Storm, and adoption of the Windows interface as a standard for personal computer models.

Book Synopsis Multi-Stage Production Planning and Inventory Control by : Sven Axsäter
Download or read book Multi-Stage Production Planning and Inventory Control written by Sven Axsäter and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper treats a two-echelon inventory system. The higher echelon is a single location reffered to as the depot, which places orders for supply of a single com modity. The lower echelon consists of several points, called the retailers, which are supplied by shipments from the depot, and at which random demands for the item occur. Stocks are reviewed and decisions are made periodically. Orders and/or shipments may each require a fixed lead time before reaching their respective desti nations. Section II gives a short literature review of distribution research. Section III introduces the multi-echelon distribution system together with the underlying as sumptions and gives a description of how this problem can be viewed as a Markovian Decision Process. Section IV discusses the concept of cost modifications in a distribution context. Section V presents the test-examples together with their optimal solutions and also gives the characteristic properties of these optimal solutions. These properties then will be used in section VI to give adapted ver sions of various heuristics which were used in assembly experiments previously and which will be tested against the test-examples.

Book Synopsis Multi-echelon Inventory Optimization in a Rapid-response Supply Chain by : Robert Giacomantonio
Download or read book Multi-echelon Inventory Optimization in a Rapid-response Supply Chain written by Robert Giacomantonio and published by . This book was released on 2013 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: The motivation for multi-echelon supply chain management at Nike is to more cost-effectively accommodate customer-facing lead time reduction in the rapid-response replenishment business model. Multi-echelon inventory management, as opposed to a traditional finished-goods only philosophy, provides two clear benefits to a make-to-stock supply chain: first, it increases flexibility through staging calculated work-in-process inventory buffers at critical supply chain links and allowing postponed identification of finished goods; second, inventories held as work-in- process are typically carried at lower cost than finished goods. This thesis details the completion of a project intended to improve Nike's ability to determine optimal inventory levels by balancing cost and service level tradeoffs in a multi-echelon-enabled environment. The goal is to develop an inventory modeling methodology for Nike's supply chain data architecture specifically to evaluate the hypothesis that multi-echelon inventory management will present only limited opportunity for cost reduction in offshore, long lead time make-to-stock supply chains. To directly asses the hypothesis, Llamasoft's Supply Chain Guru optimization software will be deployed to create an inventory optimization model for a specific family of apparel products sold as part of Nike's replenishment offering in North America. The modeling results confirm the hypothesis that multi-echelon inventory management offers little value to the current offshore supply chain. Sensitivity and scenario analysis is utilized to identify significant inventory drivers, areas for substantial improvement, and profitable opportunities for multi-echelon inventory management.

Book Synopsis Multi Echelon Supply Chain Design for Amazon Private Brands by : Shouvik Das
Download or read book Multi Echelon Supply Chain Design for Amazon Private Brands written by Shouvik Das and published by . This book was released on 2020 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Retailers across the globe continue to grow their private label portfolio to offer customers an alternative to existing brands. Typically, retailers source private label products directly from manufacturers to remove middlemen from the value chain, thereby capturing greater value and subsequently passing it on to customers. Combined with the growth of e-commerce as the primary method for consumers to shop for products, expanding private label portfolio has made e-retailers to re-think their supply chain. Amazon began its journey in Private-Label Brands (PB) in 2009 with the launch of Amazon Basics. Since then, it has expanded its presence across multiple categories. The majority of these products are imported from Asia-Pacific region (APAC) and require sourcing larger quantities to account for long-lead time between production runs and high variability in demand to maintain competitive costs. These factors result in PB inventory dwelling for a long period at the Amazon Robotic Fulfilment Centers (FCs), reducing the turns-ratio of expensive storage bins there, which could otherwise be utilized for storing high-velocity products. The growth of PB products raises the need to build more storage space, which is expensive in highly automated robotic FCs. Additionally, since fixed storage cost is proportional to the space occupied in FCs, high ‘dwell time’ translates to high storage cost. To increase utilization of FC storage bins, the Inbound Supply Chain Team plans to build a low-cost upstream storage (LCS1) to supply the FCs and store excess PB inventory there. Alternatively, Amazon can also use its third party storage center in APAC, another low-cost storage node (LCS2), after sourcing PB products from manufacturers in Asia before shipping to regional markets in US, EU, Japan etc. This could provide an opportunity for inventory savings from risk pooling by optimizing inventory storage across various nodes in the supply chain. Using multi-echelon inventory optimization techniques, this thesis explores the tradeoffs between using low-cost storage node close to end customers in the US (LCS1) versus that close to manufacturing source in APAC (LCS2). The objective of the thesis is to find the optimal inventory placement strategy across three storage points – FCs, LCS1 in US, and LCS2 in APAC - to achieve the best-in-class customer experience (InStock availability) at minimal inventory storage cost.

Download or read book Logistics Systems: Design and Optimization written by Andre Langevin and published by Springer Science & Business Media. This book was released on 2005-12-06 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a context of global competition, the optimization of logistics systems is inescapable. Logistics Systems: Design and Optimization falls within this perspective and presents twelve chapters that well illustrate the variety and the complexity of logistics activities. Each chapter is written by recognized researchers who have been commissioned to survey a specific topic or emerging area of logistics. The first chapter, by Riopel, Langevin, and Campbell, develops a framework for the entire book. It classifies logistics decisions and highlights the relevant linkages to logistics decisions. The intricacy of these linkages demonstrates how thoroughly the decisions are interrelated and underscores the complexity of managing logistics activities. Each of the chapters focus on quantitative methods for the design and optimization of logistics systems.
