An expert system shell is developed for a personal computer using C language. It is designed for diagnosis problems such as fault diagnosis and process operation guidance. The tool is suitable for the knowledge that is represented in the form of the hierarchical tree and causal relationship matrix. Further by using the tool it is easy to build expert systems which cooperatively work with the existing software by passing or receiving data, and which evokes or is evoked by external programs. Therefore the tool is appropriate to construct on-line expert systems. Application examples are shown to prove the usefulness of the tool.
