... The selection criteria include the following technology focus areas: · Process control for electronics manufacturing, i.e., the integration of in situ sensors, control algorithms, and process models and their application to critical manufacturing processes to achieve a real-time process control capability significantly beyond that possible today; and Design environments and tools needed to support the development of products from concept to fielding, including the engineering frameworks, integrated product and process descriptions, and analysis tools to support the designer. Chern, Bernard.

... computer companies formed to develop and advocate public policy positions on trade and technology issues that affect the computer industry. Its report advocates the development of a national information infrastructure, which would include a manufacturing infrastructure that incorporates computing and communications technologies to support integrated development, engineering, and manufacturing processes.

... · Recommends research on a number of specific resource management modeling methods, e.g., modeling methods based on knowledge-based systems, object-oriented systems, and Petri nets; methods that are sufficiently fast and efficient that resource problems are tractable while plants are being designed and built, as well as being operated; methods for correcting models, based on comparisons of predicted and measured performance; and many more {pp.

... Advanced Manufacturing Technology Initiative. Recommended research topics include: · Artificial intelligence and expert systems for better intelligent equipment; · Standards for data communication and mechanical, electrical, and software compatibility, to support better information linkages among cells; · Common data dictionaries for better intra-cell communication; · Open cell architecture for rapid reconfiguration; · In-process, real-time adaptive control for low variability and high quality; · Replacement materials, chemicals, and processes for making manufacturing more environmentally friendly and energy efficient; · Standards-based applications protocol data exchange for increasing data exchange capability among engineering, design, simulation, and processing; and · Communications technology for a national, publicly accessible, interactive, broadband communications network.

... Riesenfeld recommended computer science research in the following areas to advance rapid prototyping and distributed manufacturing: · Feature-based approaches to design and manufacture, and, in particular, development of a high-level, broadly applicable mode! that supports design, manufacture, and all associated processes for objects with both traditional and sculpted boundaries; · Paradigms for three-dimensional interactive specification of complex shapes for manufacturing; · Encapsulation of manufacturing "design rules," i.e., restrictions based on manufacturability, to constrain designers; · Generic approaches for specifying mechanical parts; · Sets of standard processes, fixtures, tools, stock, and so on that define standard manufacturing environments; · Efficient, effective approaches for specifying fixturing; · More powerful tools and more powerful methods for developing such tools; · Integration of design environments and manufacturing environments so that design and manufacture can be accomplished concurrently and so that a designer can accomplish all of his or her tasks within the framework of a complete, coherent, and convenient system.

... Steinberg recommended research in the following areas to support intelligent tools for designing manufacturing processes and schedules: · Guiding the manufacturing process design when there are multiple, conflicting constraints and goals; · Determining an appropriate division of labor between the human designer and the design tool; and · Coordinating multiple people and computers working on large manufacturing process design problems.

... The speakers described a number of research areas that would enhance the agility of manufacturing enterprises: · Virtual factories, i.e., the use of computer simulation to eliminate the time and cost of physically prototyping both products and processes; · Autonomous agent architecture, i.e., an enterprise architecture in which every person, system, and piece of equipment is represented by an agent; · Intelligent agents, i.e., autonomous agents that are programmed {by end users} to watch over some element of production, responding to events with actions such as shutting down a machine, starting up a program, or sending a message to another agent; · Agent-based software interoperation, i.e., software as a service available as needed over a network, rather than purchased as a system; and · EINet, i.e., a national information infrastructure supporting manufacturing, design, engineering, and analysis.
