摘要
针对复杂换热网络MINLP问题,本文应用多维函数渐变法探索和分析了连续变量和整型变量引起的网络性能非线性和非凸特性。研究表明,当系统规模增大时,不但连续变量的叠加效应将增加系统的非线性,整型变量将使得非线性特性更为严重。
In this paper, due to the MINLP problem of the complex heat exchanger networks, the multidimensional function gradient method is used to explore and analyze the heat exchanger networks non-linear and non-convex characteristics caused by its continuous variables and integer variables. The results show that, with the size of system increased, not only will the combined effects of the continuous variables enhance the non-linear characteristics, but also the integer variable will make it more serious.
