RESEARCH

Activity Areas and Support Levels

Research in the Department varies from very basic, fundamental work to the conceptualization, design, and prototype evaluation of innovative systems to serve the needs of society. The majority of the faculty are explicitly involved in basic research, and almost every research project in the Department has a fundamental component. The Department is also quite involved in interdisciplinary research. Collaborative effort in engineering systems is an important component of the department's commitment to research, since it facilitates the exchange of ideas and fosters collaboration across the traditional disciplinary boundaries of engineering. Much of the Department's interdisciplinary work is done through established laboratories and centers at MIT. These centers include the Energy Laboratory, the Laboratory for Manufacturing and Productivity, the Materials Processing Center, the Health Sciences and Technology Program, the Leaders for Manufacturing Program, the Manufacturing Institute, and the Center for Transportation Studies.

Under the leadership of Professors Asada and Hunter, the Department is now ready to launch a new interdisciplinary laboratory in information systems area. The ground floor of Building 1 will be completely renovated during the latter half of 1995 to house this new laboratory. This is due to the generous support of Mr. and Mrs. Alex d'Arbeloff.

The volume of sponsored research for 1994-1995 administered through the Department is $7.4 million. Additional sponsored research of an approximately equal amount is administered through interdepartmental laboratories and centers in which Department faculty participate. The Department continues to receive strong research support from industry and private foundations, which now accounts for approximately 45 percent of the total departmental research volume. This is a significant achievement of the faculty, especially in view of the increasingly competitive environment for research funding.
