This textbook presents an introduction into important planning problems in the area of production and supply chain management. The book focuses on mathematical models that can be used to solve decision problems that occur in practice. Topics covered in the book include material requirements planning, the planning of the production program, and the determination of optimal order and production quantities. The book also discusses problems that have to be solved on a supply chain level, such as the coordination of order and production quantities across multiple stages of the supply chain or the selection of suppliers. The textbook aims to introduce these and related problems to students in the areas of business management, business mathematics, business informatics and industrial engineering and to enable them to apply the models discussed in this book and to interpret their results.
