Recent developments of the ZEUS expert system ZEX

The ZEUS expert system project has entered its final development stage. The full system implementation will be extended to cover all of the crucial aspects of the online experiment, i.e. slow control, data acquisition performance, data quality monitoring and run control. To extend the scope of the previous version of the system OO methodology has been applied to the system design. New efficient data processing algorithms have been developed and a commercial real-time expert system shell has been used in the implementation. These issues are discussed in this paper
