Abstract

A fuzzy reasoning model is constructed and its application to contract decision making in Hong Kong is illustrated. According to professional experience, six inputs are identified as essential factors determining contract choice. They are the scale of the project, the nature of the works to be carried out, the characteristics of the client, the time constraint, the source of materials for construction and the characteristics of the building design. These factors determine whether the contract to be chosen should be in the form of a simple quotation, a lump sum contract on drawings and specifications, a schedule of rates, a management contract, a lump sum contract in standard form without quantities or one with quantities. Ten decision rules are constructed based on expert opinions. Two practical cases are investigated and presented to illustrate how the method works.

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
