Supply chain networks undergo transformations on the scale unlike any seen before. Extensive technology adoptions in supply chain networks render changes in network structures entailing multi-structural dynamics (i.e., new technologies such as Industry 4.0 and additive manufacturing lead to creating more dynamic and reconfigurable supply chains). This chapter presents an introduction to the book on supply network dynamics and control with chapters devoted to theory, methods, and applications in manufacturing, service, supply chain, and Industry 4.0 systems.
