The University of Florida will host the Thirteenth Conference on Production Research and Technology. This is one of a series of annual conferences which have been sponsored by the Production Research Program (now the Manufacturing Systems Program) of the National Science Foundation. The conferences serve several purposes: they permit assessment of the research supported by the program; they aid in program planning; and they disseminate research results to other investigators in the research community, and to potential users in industry. They also provide opportunities for investigators who want to enter the program to find out what kind of research it supports.
