This peer reviewed volume is part of an annual series, dedicated to the presentation and discussion of state of the art studies in the application of management science to the solution of significant managerial decision making problems. It is hoped that this research annual will significantly aid in the dissemination of actual applications of management science in both the public and private sectors. Volume 11 is directed toward the applications of mathematical programming to Multi-criteria decision making, Supply chain management, Performance management, and Risk analysis. Its use can be found both in university classes in management science and operations research, (management and engineering schools), as well as to both the researcher and practitioner of management science and operations research.
