摘要: A new superstructure form of heat exchanger networks (HEN) is proposed based on expert
system (ES).The new superstructure form is combined with the practical engineering. The
different investment cost formula for different heat exchanger is also presented based on
ES. The mathematical model for the simultaneous optimization of network configuration is
established and solved by a genetic algorithm. This method can deal with larger scale HEN
synthesis and the optimal HEN configuration is obtained automatically. Finally, a case
study is presented to demonstrate the effectiveness of the method.
