study on computer-aided fault tree construction for geological disasters

Using the object-oriented plat software OEC, an expert system for aiding construction of fault trees for geological disasters is developed. The friendly user interface is provided by the system. This system also affords user some other functions, such as knowledge base maintenance, following up the scent and help function. By means of the computer expert system for aiding fault tree construction, the common people can construct fault tree for geological disasters at the level of an expert, and analyzes the cause of the accidents subsequently. The principle, process of the construction and important functions of computer-aided fault tree construction were discussed in this paper.
