Qualifier-2 is a prototype knowlede-based expert system that has been developed to aid owners in making the contractor prequalification decision. The system represents a large amount of effort in the knowledge acquisition and compilation areas. A more structured approach to the process can be achieved with the use of this system. The model presents a procedure for systemizing the contractor analysis process, and is achieved by representing the prequalification problem by a hierarchy of decision parameters. A decision tree of each parameter contained in the hierarchy is implemented. This knowledge representation is coded within a commercial knowledge-based expert system shell. The paper presents a description of an algorithmic model for contractor prequalification, Qualifier-1, and its shortcomings are noted. The decision model in Qualifier-2 is described, as well as the systems structure and facilities.
