Okoroh, M I and Torrance, V B (1999) A model for subcontractor selection in refurbishment projects. Construction Management and Economics, 17(3), pp. 315-327. ISSN 01446193
Abstract
A model is presented for analysing the subcontractor's risk elements in construction refurbishment projects. The system is based on the use of fuzzy set theory with the fuzzy set representing the overall weighted average rating of refurbishment contractors criterion for the selection of subcontractors. A prototype knowledge based expert system is described, which provides a systematic and objective approach to the selection of subcontractors. Knowledge elicitation methodology using the 'repertory grid' technique is detailed. The implementation of a subcontractor selection and appointment Model for refurbishment contractors (SSARC) in linguistic terms allows the user to interact with the system in a very friendly manner using natural language expressions.

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
