PRISM (PRoductivity Improvement Systems for Manufacturing)-a CIM integration at AT&T

Abstract

PRISM, the manufacturing execution link of the overall CIM (computer-integrated manufacture) architecture at AT&T, is a family of computerized information systems supporting end-to-end shop floor operations. The work presents how PRISM supports the manufacturing operations, and describes the functionalities and architectures of the PRISM systems. PRISM supports the movement of materials from the suppliers to the shop floor, the coordination of manufacturing operations, and the dissemination of engineering information for transforming the materials into final products.<>
