Intermittent sugarcane sugar boiling and crystallization process multi-objective optimization method

The invention discloses an intermittent sugarcane sugar boiling and crystallization process multi-objective optimization method. The method comprises the following steps: 1) establishing a variable value of a first initial gene; 2) performing optimization to the first initial gene in step 1) by using a non-dominated sorting genetic algorithm to obtain a Pareto optimal solution set of final crystal size distribution parameters; 3) performing multi-objective decision making to the Pareto optimal solution set of the final crystal size distribution parameters in step 2) to obtain an optimal final crystal size distribution parameter; 4) establishing a variable value of a second initial gene; 5) performing optimization to the second initial gene in step 4) by using the non-dominated sorting genetic algorithm to obtain a Pareto optimal solution set of first crystal size distribution parameters; 6) ordering process variables corresponding to the Pareto optimal solution set of the first crystal size distribution parameters; 7) outputting results. By using the intermittent sugarcane sugar boiling and crystallization process multi-objective optimization method, better optimization results can be obtained so as to better guide the optimization control of a sugarcane sugar boiling and crystallization process.
