From Wikipedia: Integrated Computer-Aided Manufacturing:
The research in expending and applying the ICAM Definitions have proceeded. In the 1990s for example the Material Handling Research Center (MHRC) of the Stewart School of Industrial and Systems Engineering (ISyE) and University of Arkansas had included the it in their Information Systems reseach area. That area focuses on the information that must accompany material movements and the application of artificial intelligence to material handling problems. MHRC's research involves expanding the integrated computer-aided manufacturing definition (IDEF) approach to include the information flow as well as the material flow needed to support a manufacturing enterprise, as well as models to handle unscheduled events such as machine breakdowns or material shortages.
