摘　　要：提出一种用于间歇生产的多产品化工厂排序的多目标优化的混合整数非线性规划(MINLP)模型,其目标函数同时考虑了总生产时间最短和能耗最小的影响,定义了关于过程能耗的影响因子及决策因子,用以对总生产时间和能耗的影响进行权衡。采用改进的模拟退火算法(SA)对具有不同决策因子和能耗影响因子情况下的算例进行了求解,结果表明,该模型能够较好地反映能耗因素在多产品厂排序问题中的影响,使排序结果达到生产时间和能耗影响的综合最优。A mixed integer non-linear programming （MINLP） model solving a multi-objective optimization problem that minimized make span and impact of energy consumption was proposed for multi-product batch chemical process scheduling. In this model, the energy consumption factor and decision factor for various products were defined for trade-off between make span and energy consumption. An improved simulated annealing （SA） algorithm was used for solving the problem, and several cases for an example problem were studied. The proposed model could be used to show how the energy consumption consideration affects the scheduling of a multi-product batch process.
