Regional economy department water distribution balancing method and system

Abstract

The invention discloses a regional economy department water distribution balancing method and system. The method comprises the following steps: acquiring supply and demand analysis data of each waterconsumption subject; constructing a regional value objective function according to the supply and demand analysis data; constructing a regional water utilization fairness objective function accordingto the supply and demand analysis data and the regional value objective function; constructing a regional economic department water distribution balance optimization model by adopting the regional value objective function and the regional water utilization fairness objective function; adopting a non-dominated sorting genetic algorithm with an elitist strategy to optimize and solve the regional economic department water distribution balance optimization model to obtain an optimal strategy; and spatial distribution of the water resource allocation result of the regional economy department is realized according to the optimal strategy. The method can optimize and coordinate the water consumption among the industries, realizes water consumption balance among the industries, reasonably configures the water consumption, and provides important support for a water management department to reasonably arrange a water consumption plan.

Description

technical field [0001] The invention relates to the technical field of water resource allocation, in particular to a method and system for balancing water allocation in regional economic sectors. Background technique [0002] Reasonable arrangement of water use for economic production planning is an important content of water resource allocation, and also an important means to realize coordinated development of regional economy and optimize industrial structure. In the existing regional water resources planning / planning work methods, the allocation of water resources is generally based on the generalized priority or rule of domestic water use, industrial water = tertiary production and building water > agricultural water, and the remaining water is allocated. At present, there are the following problems: (1) After water is allocated by supply and demand, water shortage often only occurs in agriculture, and it is impossible to achieve water balance among various industries...

AI Technical Summary

Problems solved by technology

At present, there are the following problems: (1) After water is allocated by supply and demand, water shortage often only occurs in agriculture, and it is impossible to achieve water balance among various industries; (2) Only the proportional relationship between economic volume and water consumption can be used for water use. The estimation of economic value cannot reflect the true value of water as one of the factors of production in the production process of various industries; (3) Conventional methods generally perform subjective weighting on multiple water allocation objectives to generate a single objective function, and use specific water supply rules or Optimization methods such as linear programming solve under given constraints to obtain a set of optimal solutions

In this way, the selection of weights in the objective function is subject to arbitrariness, and the plan is too single to facilitate the comprehensive decision-making of the water management department; (4) The existing water resource planning / plan allocation method has a long forecast time and lacks short-term, inter-annual Quantitative Calculation Method of Rolling Correction
