Study on interactive multiple attribute negotiation mechanism for large-scale construction based on flexibility theory

The aim of this paper is to investigate the conflict resolution in a large-scale construction projects using multi-attribute decision-making theory and to aggregate group´s preference information. Multi-attribute decision analysis theory and flexible theory are integrated with bargaining theory to coordinate controversial issues among stakeholders in construction project when computer-based automated negotiation fails or is terminated by decision-makers in this paper. Therefore, the paper establishes an interactive multi-attribute bargaining decision model for large-scale construction projects. The interactive decision model can make the controversial issue reached an agreement acceptable to all participants by applying concessions in different objectives. Moreover, the final results are inline with the necessary requirement of group decision-making, i.e., maximizing the preference consistency of participants and minimizing the utility gaps between each negotiator´s preference and the group´s.
