An approach to a fuzzy-based decision support system for construction project teams

This paper describes a study that exploits the potential of fuzzy systems in construction through the development of a decision support system which is capable of handling fuzziness in the collaborative decision-making process. The proposed system is expected to provide an objective and rational framework within which collaborative decisions can be made by virtual construction project teams. Given the often linguistic nature of the weightings ascribed by individual disciplines to decision criteria, the proposed system will utilise the Analytic Hierarchy Process (AHP) and fuzzy systems theory to rank criteria/sub-criteria. Finally, the system will recommend an optimal decision alternative and explain the rationale for its output.
