The research and development projects focus on materials processing industries and are aimed at developing technologies that reduce the use of raw materials and energy, reduce the amount of waste generated, and increase industrial productivity and global competitiveness. Since 1993, the OIT has been undergoing a transition from a "technology push" program strategy, in which research projects are selected and prioritized primarily for their potential to reduce energy consumption or waste generation, to a "market pull" strategy, in which identified industry needs and priorities are the primary criteria for selecting projects.

The Committee on Industrial Technology Assessments (CITA) was established to review and evaluate the program and plans of the overall OIT program, review the plans and progress of selected OIT-sponsored research programs, and conduct site visits and laboratory evaluations, when appropriate, to supplement program assessments.

PANEL ON MANUFACTURING PROCESS CONTROLS The second topical panel established under CITA was the Panel on Manufacturing Process Controls. The objective of this panel was to identify opportunities for technological development that could improve process controls in the materials processing industries of the IOF and to recommend areas of emphasis for a sensors and controls initiative.

Manufacturers need to emphasize manufacturing processes, equipment, and products that improve cycle time, reduce defects, and add value while accounting for process variation. Thus, process controllers will have to provide proactive maintenance capabilities, such as measurements of performance degradation, fault recovery, self-maintenance, and remote diagnostics (Lee, 1995, 1996~.

Improved process sensing and control technology will require new scientific knowledge from material behavior to product formation for current and future manufacturing processes and the integration of manufacturing processes with design engineering and production systems. Because the overall manufacturing structures are similar for most industries, the information could be applied to many manufacturing technologies.
