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.

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.

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).

Product-driven process design – from molecule to enterprise provides process engineers and process engineering students with access to a modern and stimulating methodology to process and product design. Throughout the book the links between product design and process design become evident while the reader is guided step-by-step through the different stages of the intertwining product and process design activities. Both molecular and enterprise-wide considerations in design are introduced and addressed in detail. Several examples and case studies in emerging areas such as bio- and food-systems, pharmaceuticals and energy are discussed and presented. This book is an excellent guide and companion for undergraduate, graduate students as well as professional practitioners.

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.

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.
