东江与水库联网方案的模糊优选

Fuzzy Optimal Selection on the Collaborative Work of Dongjiang River and Reservoir Project

对东莞市东江与水库联网工程进行研究,找到最佳江库联网方案。首先采用模糊综合评判理论,利用水质等6项评判指标对三个取水方案进行比选,然后利用供水保证率等5项指标对联网线路进行优选。结果表明:沙角取水口与松木山水库相联的取水方案相对优属度最大,是最优取水方案;由松木山水库分东西两线联接形成环状闭合联网方式的相对优属度最大,是水库最优联网方式。模糊综合评判理论得到的结果能综合考虑供水保证率、环境影响、投资等多方面因素的影响,全面反映复杂的工程实际情况,取水方案和联网方式的优化结果与项目实际采用的方案一致。

Researches were conducted on the collaborative work of river and reservoir project in Dongguan to find out the best scheme of the collaborative work. Based on fuzzy optimization theory, six evaluation criteria such as water quality were used to evaluate the pumping site first and then the pipelines were optimized by guarantee rate et al. five criteria. The results show that the best pumping site scheme is Shajiao Pump Station and its connection route to Songmushan Reservoir with the superior ratio of 0. 937, the best pipeline scheme is an enclosed circle line starting and ending at Songmushan Reservoir with the superior ration of 0.972. The results based on fuzzy optimization theory can consider the factors such as water supply guarantee, environment and investment. The optimization result is the same with the result of applied in the project.
