Evaluation of flood control operation program based on extenics theory and its application

Assessing the scheduling program plays an important role in the flood control system.A comprehensive evaluation model of flood control operation has been established based on the matter-element analysis and the correlation function of the extension set. In accordance with the actual situation,the model selects typical evaluation indicators,and builds a matter-element matrix and determines the weight coefficients by information entropy-based method. The correlation between evaluation indicators and evaluation standards is quantified by the concept of Distance,which maximizes the rational utilization of feasible operation program and subjective experience of experts,and reflects the satisfaction of decision maker with the operation program. Case analysis verifies the feasibility,rationality and efficiency of the model.
