A Negotiation-Based Multi-Objective, Multi-Party Decision-Making Model for Inter-Basin Water Transfer Scheme Optimization

The planning and management decisions often involve multiple objectives and multiple parties with conflicting interests due to the complexity of inter-basin water transfer systems. In this paper, the objectives, the groups involved and the corresponding conflicting interests that characterize water transfer decisions are analyzed. A multi-party, multi-objective decision/bargaining model based on the “satisfaction principle” is developed for inter-basin water transfer system decision-making. In order to obtain an ideal multi-party decision, bargaining is first broken down into two stages, and then decision alternatives are chosen using fuzzy pattern recognition. This model is simple, and it is more adaptable for solving practical multi-objective and multi-party decision problems. Finally, an inter-basin water transfer scheme optimization example is demonstrated by using the developed model.
