Problems solved by technology

However, the chaotic optimization algorithm also has the following disadvantages: it is only suitable for unconstrained optimization and optimization problems with variable boundary values; it is only suitable for single-objective optimization problems; the initial value is used as the initial optimal solution, and the iteration efficiency needs to be improved; The larger the number of iterations, the longer the program runs

Embodiment

[0095] Taking the multi-objective optimal allocation of water resources in the Jushui Basin of Hubei Province as an example, the effectiveness and rationality of the invented method are illustrated. The Jushui River Basin is a tributary of the Yangtze River, with a total length of 170.4km and a drainage area of ​​4367.6km 2 . There are 293 large, medium and small reservoirs in the Jushui Basin, with a total storage capacity of 1.525 billion m 3 , the effective storage capacity is 864 million m 3 , including ponds and weirs, the water supply accounts for 74.2% of the total water supply from storage, diversion and provision. In this study, the Jushui River Basin was generalized into 9 water receiving areas (see Figure 4 ), and the generalized network diagram of the water resources system in the corresponding watershed (see Figure 5 ). According to the situation of the water source supply area in the Jushui Basin, there is no cross-basin water source in this area. The publ...

Description

technical field [0001] The invention discloses a method for optimal allocation of water resources based on a multi-objective chaotic genetic algorithm, belonging to the technical field of optimal allocation of water resources. Background technique [0002] The water resource system is a complex large system composed of the water resource cycle system, the water resource utilization system composed of human activities and their impacts, the ecological environment system, and the interaction of matter, energy, and information inside and outside the region. There is a complex exchange of matter, energy and information between the inside and outside of the water resource system, which jointly promote the evolution of the system; in addition, the distribution, demand, supply and consumption of ecological and economic elements in the water resource system are not uniform, and there is structural non-uniformity. Equilibrium, multiple qualitative differences between subsystems, and ...
