摘要:
合流制排水系统截流倍数的取值对水环境保护和截流改造工程的成本起着决定性作用。以不同截流倍数下的年溢流量和工程投资成本两个指标为目标函数，建立了环境-经济双目标优化的数学模型，利用加权理想点法将双目标问题转为单目标问题进行求解。理想点是多目标决策分析的方法，通过构造多目标问题的理想点和非理想点，利用靠近理想点的程度作为评价依据。通过对杭州市余杭区的案例分析得出，当截流倍数取2.63时，可以最大限度地逼近环境与经济相应的理想点，达到环境与经济的最优平衡。不同地区的工程应根据当地气候条件和工程成本，利用理想点法再次确定最优截流倍数。
Abstract:
The value of interception ratio for combined sewer system plays a decisive role in water environment protection and interception reconstruction project cost. The annual overflow and project investment cost under different interception ratios were selected as the objective functions to establish a mathematical model for environment-economy dual objective optimization, and the dual objective problem was transformed into the single objective problem and solved by weighted ideal point method. The ideal point is a multi-objective decision analysis method. By constructing ideal point and non-ideal point of the multi?objective problem, the degree close to the ideal point is selected as the evaluation basis. The case analysis of Yuhang District in Hangzhou indicated that the optimal balance between environment and economy could be achieved when the interception ratio was 2.63. The optimal interception ratio can be determined again by the ideal point method according to the local climate conditions and project cost in different regions.
