PROMA-A Decision Support System to Determine Appropriate Procurement Method

The aim of this study was to develop computer application software using the weighted sum model equation to assist construction industry practitioners in making analytical decision about building procurement options. A survey of construction industry practitioners in Nigeria was conducted to prioritize the selection criteria and determine the utility factors for the procurement options against selection criteria. The results were used to populate the software. The program uses clients’ consultants’, contractors’ or the combined utility factors for cost categories to recommend an appropriate procurement method for a particular type of building. This makes the program better than earlier works which ignored the effect of cost categories on procurement options’ performance.
