The goal of this session is to provide an introduction to the problems and methods of SCM, focusing on the matching of supply and demand in complex, variable, and/or uncertain environments. To illustrate the widespread applicability of SCM, our speakers consider problems in a variety of settings, including manufacturing, the military, security, and public policy. These papers will provide examples of some of the work being done in SCM. However, potential applications of SCM methods could also include many other areas, such as water-resource management, certain nanoenvironments, network design of electrical systems, and so on.
