Research And Application Of Decision Support System For Scheduling Of Complicated Flood Control System

The united scheduling of basin flood control system is an important non-structural measure of flood mitigation to improve flood control ability of basin engineering system. A research on decision support system for basin flood control scheduling is presented by a case study of complicated flood control system of downstream basin of the Yellow River including reservoir, river channel, flood diversion area and flood detention area in this paper.In this paper, the development process of basin flood control scheduling research is systematically summarized, and definitely indicates that the decision support system for flood control scheduling is a hotspot of current research.Aim at ubiquitous parallel multi-reservoir structure in our country's basin, the universal objective function including coefficient Bi embodying a spatial significance difference at different flood control points and variable ai denoting a selection of scheduling mode is established, which provide a valid intervenor interface for flood control consultation decision. According to the real-time requirement, a model of reservoir storage allocation is proposed, which embody basic idea of phasic compensation. Passing the dynamic correction to cut down the disadvantageous influence that indetermination result in on the certain degree, joining together the step alternation solving method, this model can maximally consider bias of decision makers, ensure the rationality and practicability of the solutions.In this paper, the total design of decision support system for basin flood control scheduling is systematically described; the decomposing principle for complicated flood control system is proposed, a models library satisfying the different requirement is established, and the quick creation of scheduling scheme and build of consultation and analysis system is thoroughly studied.By choosing flood control system of downstream basin of the Yellow River as the background, six relatively independent subsystem is established, which includes basic information management, real-time flood forecast, multi-reservoir flood control scheduling, consultation and analysis, scheduling scheme management, frequency analysis, and assist with friendly man-machine conversation to constitutes the Yellow River downstream flood control scheduling decision support system, which can satisfy the practicability requirements of decision-making.
