Abstract: To address the dynamic changes in competitive relationships among multiple objectives in real-time watershed water resource scheduling, this study proposes a real-time decision-making system aimed at enhancing the synergy of multi-objective water resource allocation and the scientific rigor of decision-making outcomes. The technical core of this system was the real-time scheduling decision technology for watershed water resources based on scenario-target interaction, constructing a multi-objective decision function, combining scenario recognition and weight adaptive allocation mechanism, coupling water quantity and quality mathematical models with water resources scheduling decision models, and constructing a real-time scheduling decision system platform for watershed water resources. The main functional modules of the platform included scheme management, numerical simulation calling, scenario recognition, intelligent decision-making, decision evaluation, etc. The platform supports real-time decision-making for watershed water resource scheduling under changing scenarios, and provides decision-making references for scientific scheduling and management of watershed water resources.
