Knowledge-Based System Analysis and Control Defense Switched Network Task Areas

A major activity during FY90 has been the design and implementation of a network management expert system to operate in the integrated Workstation IW that was developed during FY90 for use by ACOC personnel at DCA-Eur to perform DSN network management tasks. The IW was successfully tested on live and archived data, and on fault conditions deliberately induced by switch technician actions, during the period 25-28 September 1990. All parties declared that the IW features and demonstrated performance were valuable and successful. The Expert System was well received, in particular. An IW terminal has been installed on the floor of the ACOC, and the staff have been directed to familiarize themselves with its operation. A number of changes and improvements were made in CCSIM and related programs. All were converted to run under SUN OS 4.0.3. The graphics interface program was rewritten to use the X-window system. A new document called Using The Call-By-Call Simulator CCSIM has been written, and the CCSIM Users Manual and the CCSIM Software Top Level Design Document delivered in FY90 are to be updated early in FY91. Work performed in expert systems development efforts for DCS transmission system control two main components implementation of the TRAMCON Event Generator TEG, and participation in the Tech Control Automation Proof-of-Concept System TCAPS. TEG has been specified during FY89, and has now been written and successfully installed and demonstrated at a number of locations. Lincolns RADC-sponsored MITEC expert system was incorporated in a DCA-sponsored set of TCAPS field demonstrations.
