Based on a superstructure representation , a nonlinear programming ( nlp ) model as well as a mixed - integer nonlinear programming ( minlp ) model was proposed in this paper for the optimal design of distributed wastewater treatment network system 摘要基于分散式廢水處理網(wǎng)絡(luò)的超結(jié)構(gòu),建立了廢水處理網(wǎng)絡(luò)系統(tǒng)最優(yōu)化的非線性規(guī)劃模型和混合整數(shù)非線性規(guī)劃模型。
