This book presents recent developments in theory, methodology and technique in the field of planning and scheduling of production systems. It aims to promote understanding of the fundamental precepts and their application in practice, providing the reader with the ability to answer the following questions: which are the appropriate approaches to use in a particular situation? how are they used and what are the pitfalls? what does the future hold in the field and what do I need to know to cope with it? The work explains "what" the different approaches are, and "how" and "when" they are applied. It is an ideal source of information for both practitioners in planning and scheduling and students studying industrial engineering, management science and manufacturing.
