Cachon Matching Supply with Demand 4e is a clear, concise and more rigorous approach to an introductory Operations management course. Written by Wharton authors who use their guiding principles "real operations, real solutions" to bring the text and concepts to life, writing the majority of chapters from the perspective of specific companies. The "real solutions" refers to providing students with tools and strategies they can implement in practice and apply the authors models in a realistic operational setting. The authors strive for "real simple" by using as little mathematical notation as possible, focusing on many real world examples and consistent terminology and phrasing throughout.
