The scope for pollution prevention in the process industries is wide. The gap between actual performance and possible performance must be addressed through an integrated approach involving the regulatory process, executive level management, and the application of technology to design integrated production facilities. Technology currently exists to achieve this objective. The challenge is to identify and deploy the technology. The technologies for designing integrated processes can be placed in three categories: 1) hierarchical review and other methods of structured thinking, 2) mathematical, and 3) thermodynamic. Senior management has a particularly critical role to play in pollution prevention. They must quantify the opportunity (the performance gap) for their own facilities, identify which technologies will address the problem, and develop and implement strategies for achieving their objectives.

Technology per se does not provide a competitive advantage. Timely exploitation of technology is what gives the competitive edge, and this demands a major shift in the product development process and management of the industrial enterprise. `Teaming to win' is more than a management theme; it is the disciplined engineering practice that is essential to success in today's global marketplace. Teaming supports the concurrent engineering practices required to integrate the activities of people responsible for product realization through achievement of shorter development cycles, lower costs, and defect-free products.

The increasing sophistication and criticality of embedded flight control systems is increasing the need for correct system implementation/error removal before flight control systems are fielded for flight. Competing with this need are pressures to make corrections and design changes quickly to minimize the cost and schedule impacts during development, especially ground and flight test activities. In this paper we will present a system designprocess modified to allow the use of a currently available system design tool that provides automatic code generation from graphical system design input to provide a portion of the flight software. The results are improved system design, accelerated integration times and the ability to correctly implement changes in a shorter period of time. The value of integrated system design/code generating tools will be addressed. Modifications made to the current designprocess to integrate and verify software produced by these tools in the flight program will be addressed. Finally, results obtained through the use of this process on a number of current flight control system efforts will be summarized.

It is generally acknowledged that technologies diffuse through industry and that the rate of diffusion varies both within different industries and according to the circumstances. Innovation is a process involving risk, especially during the adoption and adaptation of a powerful new technology. Central to a consumer products success using new technology is the quality of their designs and the nature of their forms. Form is of prime importance in influencing the purchasing decisions of consumers and it is also influential in determining the relationships between people in its use environment. The acceptance of a new product into the world is often unduly ad hoc. Many failures are created for each success and there are few guidelines to assist the formulation of a strategy for creating an appropriate form. It is suggested below that success of consumer products incorporating 'smart structures' may be determined not only by the function of products and systems, but also by the form they take. The definition of a desirable product form depends entirely on the point of view taken: technological, commercial, ecological, cultural, and social. However any design using new will incorporate the old and the new. The probability of acceptance of a new product is enhanced by maintaining a fine balance between imaginative and creative form and that with which people are familiar and prefer: a new design may be rejected if it is too novel and unfamiliar, or too traditional. The acceptance of a new product and its subsequent development depends on the success designers and engineers have when dealing with the initial forms, particularly using new technology such as 'smart structures'.

A challenge for engineering education in the 1990s is the integration of additional design content into the curriculum. design work allows students to own their learning through defining problems, creating ideas, evaluating them against constraints, and building models. The process engages students in team work and communication. design education creates an environment where students can learn independently and develop the thinking skills necessary for problem-solving in their professional work. We discuss our approach to creating this environment in Miami's Computer-Aided Experimentation course. The course integrates concepts of computer control, instrumentation, and experiment design in both lecture and laboratory. design is part of the lab experience. The lab has three parts: 1) introduction to experiment design, 2) computer-machine interface systems, and 3) design projects. An essential aspect of this experience is for students to conduct open-ended team projects to design, build, and test systems utilizing computers, sensors, and data acquisition. As examples, we describe three insect robot projects. These are miniature robots capable of simple autonomous behavior. The experience base from four years of such projects has served as both a teaching tool and as the bases for subsequent projects. The projects reflect our philosophies toward effective pedagogy and student design work.

This paper describes the integration of water quantity and quality objectives within the framework of a computerized interface design to assist with the difficult process of long-range river basin planning under competing water demands. The approach accounts for uncertainty in model predictions of system behavior resulting from temporal and spatial variability and inadequate data associated with model parameters. It emphasizes simulation-based assessment of strategic planning alternatives through the use of graphics and expert systems interfaces. Performance measures were developed to facilitate the evaluation and comparison of alternatives in light of planning objectives.
