The application of expert systems in the construction industry requires the use of general-purpose computers, such as microcomputers, minicomputers, and mainframes. The use of commercial expert system shells allows for a focus to be placed on the knowledge base, rather than the programming aspects of development and delivery. Stand-alone expert systems applications provide consultative environments for end users, in a manner that closely emulates the type of consultation that the user might have with the human expert. Examples of such systems include the Welding Procedure Selection Advisor, and the Weld Defect Diagnosis expert system. In contrast, applications which integrate the use of engineering design with expert systems require more sophisticated software environments. The use of integrated design/database/expert system applications will create opportunities for more consistent, efficient design and construction processes.
