Fundamentals of Supply Chain Theory

John Wiley & Sons, 11-Jul-2019 - Business & Economics - 784 pages
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 and quantitative approaches 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, 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.
