The Fourth International MCDM Conference follows a tradition that began with an exploratory gathering at the University of South Carolina in 1973. The First International Conference was held in Jouy-en-Josas in 1975. The second and third were held in Buffalo (1977) and KOnigswinter (1979). We are grateful to the Office of Naval Research for years of advice and funding, and to Springer-Verlag for providing a widely dispersed series of proceedings volumes. In the case of the Delaware Conference we gratefully acknowledge new support from the corporate sector, coordinated by the University of Delaware's Development Office.

" From Erick Duesing, speaking with an historical perspective, we had the insight that multiple criteria methods lan guished because "McCarthyism had made planning suspect."
