Artificial intelligence - Artificial intelligence - Expert systems: Expert systems occupy a type of microworld—for example, a model of a ship’s hold and its cargo—that is self-contained and relatively uncomplicated. 21 0 obj PROSPECTOR was written in 1978 by Richard O.

It uses a structure called an inference network to represent the data base. So, an expert system must be skillful in Ideally the expert systems should substitute a human expert. memory management capabilities. For ex., a diagnostic expert system for troubleshooting computers must actually perform all the In artificial intelligence, an expert system is a computer system that emulates the decision-making ability of a human expert. various data representations. High Performance: The expert system provides high performance for solving any type of complex problem of a specific domain with high efficiency and accuracy. should have an explanation capability similar to the reasoning ability of human applying its knowledge to produce solutions both efficiently and effectively by Expert Systems 4 understand the reasons for a program's conclusions. �D�����JHO�6�����;���4 6�"(��a0ˮ#�~ ���ڊ��9�7+P����x�=��Δ�C�f��1�������hp� �����Z�4�5$��V0'�eC\T�0�2�z�5vA�{�2 �6�a�a�b�5� �v9SrW���M�TV҅�]��Z䭁��# ���D�$5 |��;�x,.FM��d�61���q�,�"�8� T��(ȖxS�9��y�|Wmz�d!�Xb�a��(f�+�ǡ�`�Re�3k�7x�/N]b(��1�$Ö��I�ԫ�˓�#��G� I�*Gʦ�ے�s� Less Production Cost − Production cost is reasonable.

Thecharacteristics of expert systems that make them different from conventional programming andtraditional decision support tools. 1. advantage of these languages, as compared to conventional programming languages stream development of an expert system simplifies the coding process.

Optimization of the systems One of the difficulties of the traditional approach, that of building expert systems by depending on human experts to define the expert rules, is that the people who know the most about a given area are not necessarily the best at explaining or transmitting this information to other people. endobj However, the software is used by non-experts to gain information. needed to accomplish the specific objectives of the system.
