Russell, J S; Skibniewski, M J and Cozier, D R (1990) Qualifier-2: Knowledge-based system for contractor prequalification. Journal of Construction Engineering and Management, 116(1), pp. 157-171. ISSN 0733-9364
Abstract
Among other concerns, contractor prequalification involves the evaluation of a candidate contractor’s reputation, past performance, financial stability, experience record, firm capacity, current workload, and technical expertise. Qualifier-2, a prototype knowledge-based expert system that aids construction owners in performing contractor prequalification, is presented in this paper. A description of a previously developed algorithmic model for contractor prequalification, Qualifier-1, is also discussed and its shortcoming are outlined. The hierarchical decision model applied in Qualifier-2 is described along with sample decision rules implemented within the developed system followed by a description of the prototype system’s structure and facilities. The system prompts the user for pertinent contractor data and performs the evaluation. A help, explanation, and recommendation facility have been included to aid the user during a consultation. The system provides an automated contractor evaluation process through which rational and consistent prequalification decisions can be made.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
