Design Of Expert System For PABX Fault Diagnostic

The article introduces the status for PABX fault diagnostic method, deeply analysis the structure of the PABX faults , find out the procedure which is used to solve the problem. Through apply the software project method, and artificial intelligence, designed a expert system of the PABX fault diagnostic. The core technology is that we use the object oriented theory at the field of expert system, so the architecture is more clear, the implementation of design is more easy, the maintain and extension of the project is more easy too, in the future, we can make the method more integrity and extended it, apply it to other AI system, at the article, we discuss detail of the implementation of class and object with knowledge presentation and inference machine.The result is the design of expert system for PABX fault diagnostic, prototype and the comment of it. After the experts of PABX use the prototype, they give the following comments: the system is fulfill the requirement of the PABX experts, easy operation, and the knowledge of the PABX expert is easy transfer into computer, it will bring huge profit in vary fields such as shorten the time of dealing with PABX fault, reducing the lose of expert knowledge or the oblivion, lower the cost of the human resource, and it will be a commercialproduction to sell to the enterprise group, it is a successful computer aidedexpert system.
