The invention discloses a multi-target optimization control method based on a dynamic variable value and belongs to the field of modeling and optimization control of complex industry processes. According to the invention, based on a sewage processing mechanism model, by improving a traditional control method, designing 3 dynamic variable value tracking controllers and carrying out dynamic optimization on setting values of each controller in each optimization period, dynamic variable value tracking control of dissolved oxygen concentration of fourth and fifth reaction units and nitrate nitrogenconcentration of the second reaction unit is achieved, so a problem of big tracking difficulty in traditional control mode is solved; by taking the setting values of the controllers as auxiliary variables, soft measurement modeling of energy consumption and penalties is performed; and finally, by use of an intelligent decision multi-target particle swarm algorithm, optimization is performed on setting values of the controllers, so an optimal setting value combination in each optimal period is obtained, the effect of balancing two indexes of energy consumption and discharged water quality is achieved, and under the premise that the discharged water quality is ensured, the energy consumption and penalties are kept in a quite low level simultaneously.

The invention relates to a newsboy model for optimal allocation of water resources considering uncertainty of supply and demand. The model includes: S1, the runoff variation rule is obtained by usingthe measured hydrological data, and the probability distribution of runoff is obtained by statistical analysis; S2, according to that classic newsboy theory and according to the characteristic of agricultural, industrial and domestic water, the three types of water demand are assumed to be uniformly distribute, and the data of the previous three years are used as historical data for rolling forecast of water demand; S3, by using the probability distribution function of incoming water and water demand and introducing the newsboy model of economics, the newsboy model of optimal allocation of water resources considering the uncertainty of water supply and demand is constructed, and the preliminary allocation scheme is solved.; whether the total allocation water quantity exceeds the maximum available water quantity is judged, if not, the initial allocation plan is the optimal plan; if it exceeds, the two-stage heuristic algorithm is used to solve the problem again to obtain the optimal plan. The method provided by the invention can obtain a water resource allocation scheme which is closer to the actual situation of water demand.

The present invention relates to the field of water resources management and more particularly to a method for optimal allocation of water resources based on a feedback mechanism The method includesthe steps of constructing a basic model of water resources allocation, and obtaining initial water resources allocation scheme by using conventional water resources allocation method; 2, applying theinitial allocation scheme to the actual hydrological situation, since the water demand cannot be accurately predict, the initial allocation water quantity being deviated from the actual water demand,and the allocation deviation sequence is obtained; 3, constructing a feedback gain function and obtaining a gain amount by using a deviation sequence; S4, adjusting the initial configuration scheme ofthe future period by using the gain amount, and obtaining the feedback configuration scheme The method can save water resources efficiently and reduce the engineering quantity of water resources management effectively, which is of great significance for water resources management

Optimal allocation of water resources based on feedback mechanism

The invention relates to the field of water conservancy projects, in particular to a total water consumption control-based newsvendor method for the optimal allocation of water resources. The method comprises the following steps: S1, collecting water supply quantity data and water requirement data according to water distribution transferring conditions and demands for water; S2, determining the objective function and the water distributing coefficient through combining with the data collected in the step S1 and taking the comprehensive benefit of the economy, the society and the ecological environment as the maximum goal; S3, forming constraint conditions of the optimal allocation of the water resources according to data conditions in a water resource simulating system; and S4, solving a total water consumption-controlled newsvendor model for the optimal allocation of the water resources. The method disclosed by the invention has the advantages of closely integrating a current social proposition of controlling the total water consumption with dynamic change information of water market price, reflecting the influence of different total water consumption controlling index schemes onthe net income of water users, effectively coordinating relationships among drainage basin water, water demand and total water consumption control and water distributing indexes and according with water consumption characteristics of southern areas with high water consumption intensity.
