【Abstract】 For the purpose of improving the performance of methanol synthesis optimization process with multiple objective functions, the multi objective genetic algorithm is modified in this paper. Multi individual crossover operator and mutation operator among populations are introduced and multi objective weighing factor is used for solving problem of constructing adaptive functions, resulting faster running speed and better agility and showing good performance in its practical applications.更多还原
