Expert system may be classified into various groups depending on the
types of problem they can solve:
- prediction-systems-weather forecasting, financial forecasting, agricultural estimates.
- diagnostic systems-medical, software and elctronic problem diagnosis.
- design systems-assissting in the design of buildings,electronic circuits and manufacturing processes.
- monitoring systems- security, maufacturing and air traffic control.
- maintenance systems- detecting and repairing faults in electronic systems
Advantage:
The advantage of an expert system over a book written system is that the expert system will actively solve problems itself, rather than simply stroing the knowledge.
Disadvantages:
Cannot adapt to changing environments, unless knowledge base is changed, Errors may occur in the knowledge base, and lead to wrong decisions
