Multiagent organizations for real-time operations

Article Abstract:

Real-time operations of electric power networks are complex and important and are becoming increasingly more sophisticated as new technologies and socio-economic factors increase size and add new dimensions. Rising levels of utility interaction, deregulation movements, the growing number of nonutility generators and growing environmental concerns are all contributing towards the complexity of real-time operations. Computer-based multiagent systems in energy management systems (EMSs) can help add new functionality and will help real-time operations keep up with new complexities. The new generation of EMSs have opened up distributed computing environments. The power industry is working to open up standards for communications and interfaces. Organizations need to change in order to bring about new functionality. Three types of organization structures for EMSs in the future include blackboards, scientific communities and insect societies.

The Engineering Design Research Center of Carnegie Mellon University

Article Abstract:

The Engineering Design Research Center (EDRC) at Carnegie Mellon University is intended to make a significant contribution to design science through methodologies, computational tools, and environments for engineering design. It is also meant to educate a new generation of engineering design practitioners, educators, and researchers for industry and academia, and to develop engineering design textbooks and other course material, courses, and an optional undergraduate minor in engineering design. The center also collaborates with industry to support improved design practice through the exchange of knowledge, people, and software tools. The three specific research goals of the center's strategic plan are to develop unified representations of goals, constraints, behavior, and structure in various domains; to build comprehensive single-domain design testbeds; and to develop multidesigner multidomain testbeds.

Architecture of fault-tolerant computers: an historical perspective

Article Abstract:

A look back at the history of computer design reveals that the average time between failures for computers has increased by three orders of magnitude. Several different approaches to fault tolerance have been tried over the years, and fault tolerance has become even more important because so many sectors of the economy rely on computers. Designers of fault tolerant machines first looked to the causes of failures in their attempt to create systems that could eliminate outages. Among the trends in current fault tolerant computer design include using software for isolation and recovery, multiprocessing systems with dynamic redundancy, masking techniques, and using hardware for error-detection.
