In this study, a multiobjective optimization approach was adopted to optimize pumping operations by minimizing energy cost and greenhouse gas (GHG) emissions while considering water quality either as an additional objective or as a constraint. When water quality was not included, a trade‐off between energy cost and GHG was found. Including water quality as a constraint led to an overall increase in energy cost and GHG emissions while keeping trade‐offs between the objectives. When water quality was included as a third objective, there was a positive correlation between energy cost and GHG emissions, but a negative correlation was found between water quality and the other two quantities (energy cost and GHG). The three‐objective formulation enabled a deeper understanding of each individual solution, while also providing a wider range of possible alternatives to consider.

优化水分配系统中的泵操作:能源成本,温室气体排放和水质

在这项研究中,采用了一种多目标优化方法,通过将能源成本和温室气体(GHG)排放降至最低,同时将水质作为附加目标或约束条件来优化泵送操作。如果不包括水质,则会在能源成本和温室气体之间进行权衡。将水质纳入约束范围会导致总体上增加能源成本和温室气体排放,同时在目标之间进行权衡。当水质被列为第三个目标时,能源成本与温室气体排放之间存在正相关,而水质与其他两个数量(能源成本与温室气体)之间存在负相关。三个目标的表述使您对每个解决方案都有更深入的了解,
