For pt.2 see ibid., p.71-9 (1996). The Archon distributed AI software framework integrated two preexisting standalone systems into a consistent, flexible application. The integrated systems provide useful information to each other and improve each other's performance through cooperation. The authors describe the use of the Archon framework to build a distributed AI application for controlling, and diagnosing faults in the Proton Synchrotron, one of CERN's (the European Laboratory for Particle Physics) particle accelerators. The PS complex is the heart of CERN's accelerators and experimental facilities and also acts as an injector for the larger accelerators.
