Which contractor selection methodology?

Industrial and academic awareness of the need for judicious construction contractor selection is increasing. Earlier investigations of this client procurement decision have more recently been expanded upon; particularly, by work conducted in the USA and UK. Other countries are now also addressing this issue and procurement research abounds. This paper complements that increased activity by presenting a review of contractor evaluation and selection modelling methodologies. These methodologies include: Bespoke approaches, Multi-attribute analysis, Multi-attribute utility theory, Cluster analysis, Multiple regression, Fuzzy set theory, and Multivariate discriminant analysis. The merits/demerits and previous/possible future applications of each methodology are discussed, and indications for future research given.
