Real-time data transfer in an intelligent CIM node

A major step toward resolution of two of the major problems in CIM applications, real-time data transfer and uncertain information, is presented. The approach to real-time data transfer, including handling of asynchronous priority interrupts, is accomplished by introduction of an intelligent interface node connected to the primary data communications channel or information systems backbone. A secondary communications channel is developed for this purpose. In simulation runs, the intelligent interface node was able to satisfy 99.1% of the real-time data transfer resource shortfalls that otherwise would have resulted without implementation of the knowledge-based expert system, including all of the highest-priority data transfers. Resolution of uncertain information is accomplished by use of the MYCIN shell, modified for the specific purposes of CIM implementation
