Study On The Optimal Allocation Of Municipal Multiple Water Resources

This study is mainly focused on the optimal allocation of municipal multiplewater resources, and it is aimed to reach the total optimization of the societalbenefit, economic and environmental one based on the theories of system analysisand multiple objectives optimization.Firstly, the evolution about water resources optimal allocation study issummarized, and the limitation and shortage on this field is analyzed.Secondly, in allusion to the above issues, the city water resources optimalallocation theory is identified based on the aim frame system of the city'scontinuable development, which can reflect the integrated development of thecity's economy, community and environment. Accordingly, the theoretical basisfor the optimization model is established.Thirdly, a new optimal allocation model is established based on the formeranalysis. In the new model, the optimal objective function is multi-objective, thatis, the benefit of city water supply, the emission amount of the main pollutant, thecommissariat output of the suburb, the number of people who are working and theamount of the entironment water. In the meanwhile, the model decision variablesare water amount and the acreage of crop.Fourthly, comparing all the known model solution methods formulti-objective optimization, the author decided to adopt the interactive multipleobjective-allowance restriction method.In the end, according to the optimal allocation model, the author designedand complied computer application program on Delphi platform, which linkedLingo software for model solution, and the model is applied to a hypothetical city,which proved that the result is feasible and reasonable. Finally, it is concluded thatthe way can be applied to the optimal allocation of other resources.
