Abstract: The present invention provides a multi-objective optimization method and a device for catalytic cracking process, and a computer-readable storage medium. The multi-objective optimization method comprises following steps: determining a plurality of optimization objectives, a plurality of process decision variables corresponding to the plurality of optimization objectives, and a constraint range of each of the process decision variables; determining an objective function according to the plurality of optimization objectives and the plurality of process decision variables; adjusting a value of each of the process decision variables within the constraint range by SPEA2 algorithm, which improves filial generation evolution process through a path-based reproduction operator, thereby determining an operation data of the objective function on each of the process decision variables; determining an optimization objective value of each of the optimization objectives according to the operation data of each of the process decision variables; and determining the operation data as guide values of the plurality of process decision variables, corresponding to the plurality of optimization objectives, according to an optimal optimization objective value solution set.
