With the increasing complexities in supply chains and increasing global trade, integrated supply chain network design is utilized by the firms in order to reduce the overall cost while meeting the customer demand with requisite levels of service. This view of collaborative approach towards supply chain design has the potential of providing competitive edge for the firms in a highly competitive environment with high variability of end customer demand. In this study we present a framework for the design of a multi echelon supply chain network facing uncertain demand. We develop a comprehensive procedure for the optimization of a multi echelon supply chain. We provide the details of each step to describe the methodology and develop mathematical models for the design of a multi echelon distribution network. The procedure has been developed for the design of network flow and the placement of safety stock for a multi echelon distribution network.

The objective of this study is to develop prescriptions for strategically placing safety stocks in an arborescent supply chain in which there are moderate to severe risks of disruptions in supply. Our work builds off of recently published work by Graves and Willems (2003) that demonstrates that a simple-to-compute, congestion-based adjustment to supply lead times, first developed by Ettl et al. (2000), can be embedded in a non-linear optimization problem to minimize total investment in safety stock across the entire supply chain. We are interested in investigating how the Graves and Willems (GW) model performs under uncertainty in supply. We first propose an adjustment to the model (Mod-GW) by considering two types of fulfillment times, a normal fulfillment time and a worst possible fulfillment time, which allows us to account for supply uncertainty, or disruptions in supply. We evaluate the performance of GW and Mod-GW using Monte Carlo simulation and, using motivation from Timed-Petri Net analysis, develop an Informed Safety Stock Adjustment (ISSA) algorithm to compute the additional buffer stock levels necessary to improve downstream service performance to the target level. We find that the service performance of the Mod-GW solution is most sensitive to the probability of disruption at any node in the supply chain, requiring higher safety stock adjustments through ISSA as this probability increases. In particular, the relative value of the holding costs for components and finished goods--and the resulting impact on where safety stock is held in the network--is an important moderating factor in determining the level of service performance degradation of the Mod-GW solution as either, the probability of disruption at node j, or, the ratio of the disrupted and normal lead times, increases (i.e., as disruptions exert more impact on the network). The Informed Safety Stock Adjustment algorithm generally suggests a sufficient complementary amount to the saf.

Inventory Management in Multi-Echelon Networks presents methods to plan inventory in distribution networks. By holistically looking at the supply chain, it shows how safety stocks across all echelons can be optimized if inventory of all levels is taken into consideration. The gap between the existence of advanced inventory planning methods and their low penetration in the industry was the motivation for this book. Christopher Grob develops essential algorithms that companies can use for network inventory planning and highlights achievable implementation benefits. The work of the author was inspired by the needs of an after sales supply chain of a large automotive company. This company supplies customers all over the world with spare parts and operates a distribution network with more than 100 warehouses. This supply chain faces two particular challenges: demand is highly uncertain and customers expect a high service level. About the Author Christopher Grob works in after sales supply chain management at a major German automotive company. He is responsible for the functional development of inventory planning systems for the spare parts business. He is an expert in the field of inventory management.

Increasing customer requirements, product variety, and market competition demand for service and cost improvements by model based inventory control in supply chains. The book presents approaches for safety stock determination in manufacturing and logistics networks. Most of the existing literature provides methods for very specific types of supply networks. The approach presented in this book follows a material flow philosophy that allows for several extensions of the basic models and therefore offers a wide applicability within decision support systems. Models for several types of problems and network structures are presented and analyzed to develop efficient optimization algorithms and heuristics.

Comprehensively teaches the fundamentals of supply chain theory This book presents the methodology and foundations of supply chain management and also demonstrates how recent developments build upon classic models. The authors focus on strategic, tactical, and operational aspects of supply chain management and cover a broad range of topics from forecasting, inventory management, and facility location to transportation, process flexibility, and auctions. Key mathematical models for optimizing the design, operation, and evaluation of supply chains are presented as well as models currently emerging from the research frontier. Fundamentals of Supply Chain Theory, Second Edition contains new chapters on transportation (traveling salesman and vehicle routing problems), integrated supply chain models, and applications of supply chain theory. New sections have also been added throughout, on topics including machine learning models for forecasting, conic optimization for facility location, a multi-supplier model for supply uncertainty, and a game-theoretic analysis of auctions. The second edition also contains case studies for each chapter that illustrate the real-world implementation of the models presented. This edition also contains nearly 200 new homework problems, over 60 new worked examples, and over 140 new illustrative figures. Plentiful teaching supplements are available, including an Instructor’s Manual and PowerPoint slides, as well as MATLAB programming assignments that require students to code algorithms in an effort to provide a deeper understanding of the material. Ideal as a textbook for upper-undergraduate and graduate-level courses in supply chain management in engineering and business schools, Fundamentals of Supply Chain Theory, Second Edition will also appeal to anyone interested in quantitative approaches for studying supply chains.

The placement and sizing of safety stocks in supply chains pose a challenging optimization problem. State-of-the-art multi-echelon inventory optimization models, such as the guaranteed-service approach, are non-linear and depend on statistical, time-series-based approaches that require distributional and parametric assumptions. We propose a data-driven, non-parametric and distribution-free approach for safety stock planning in multi-echelon inventory networks that utilizes historical demand and feature data. We extend data-driven optimization in inventory control from newsvendor models to multi-period and multi-echelon problems. Our model accommodates general, acyclic multi-echelon networks and simultaneously determines safety stock allocation and sizing by setting cost-optimal base stocks for all stages under consideration of service requirements. By developing a mixed-integer programming formulation and a Benders decomposition method, we offer a novel methodological approach to a well-studied problem that can be solved with commercial mathematical programming solvers. We also provide a probabilistic analysis of the data-driven performance relative to an oracle solution when sample data is limited. We show that the mixed integer programming approach is scalable by solving 38 large-scale supply chain benchmark networks with assembly, distribution, and general structures.
