The ZEUS detector is controlled and read out by a highly parallel distributed online system. In July 1992 the ZEUS collaboration decided to launch an expert system project aimed at increasing the efficiency and reliability of operating the experiment while reducing the required manpower and expertise of the shift crew. 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 on-line 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.
