Multi-Attribute Utility Model for Selection of Appropriate Procurement Method in the Construction Projects

The selection of an appropriate procurement method is becoming an increasingly important issue due to complex decision-making that has to be made by clients early in the project lifecycle. The aim at this paper is to improve and enhance procurement system in the construction industry through developing a model using the multi-attribute utility theory (MAUT) as a decision support system for the selection of appropriate procurement method for construction projects in the Gaza Strip. Factors that influence the selection of an appropriate method for construction projects in Gaza Strip were identified. The results indicated that the top significant six factors that have most influence on the selection of procurement methods in the Gaza Strip construction projects are: price competition, degree of project complexity, time constrains of project, project size, client's financial capability, and client's experience in procurement methods. The study concludes that there is no variety of procurement methods used in the Gaza Strip construction industry where a traditional procurement method is preferred. This is because most of professionals' in Gaza Strip are not familiar and not widely experienced with the other alternative procurement methods. A model was developed using Multi Atrribute Utility Theory to select the most appropriate procurement method. The multi-attribute utility -theory (MAUT) as a decision support system was able to identify the appropriate procurement method.
