A great deal of attention has been directed towards the studies of individual procurement method, however few studies have focused upon a direct investigation of the factors affecting the choice of a particular procurement method. This paper reports a research study carried out in Australia on procurement selection. The study, based on a multi-attribute approach, aimed to develop an expert system to aid the selection of the most appropriate procurement system. A procurement categorisation was developed to reflect the current procurement practice in Australia. The model is based on a set of utility factors derived from three local experts. A concordance analysis was used to check any abnormal data sources. Twenty six case studies were carried out in which clients were asked to indicate the relative importance of each criterion in the system. The most appropriate procurement method recommended by the model was computed and compared with the actual choices made by the respective clients. 54% of the cases were found to have the first two recommendations matching the actual selection. This demonstrates some encouraging results and suggests a favourable possibility of developing an expert system to select procurement systems.
