Abstract

The invention relates to a system for intelligently switching car systems of a blast furnace loading system. The system comprises an encoding module, an initial population generation module, a selection module, an intersection module, a mutation module and an optimizing module. The encoding module conducts real number encoding on decision variables, the initial population generation module substitutes randomly-generated decision variables into an objective function to generate initial individual populations, the selection module selects parent individual populations from the initial individual populations according to a fitness proportion method, and the intersection module randomly selects two parent individuals from the parent individual populations and conducts intersection exchange on decision variables of the selected parent individuals, and offspring individual populations are obtained through multiple times of random selection. The mutation module mutates decision variables of the offspring individual populations, and the optimizing module makes a found local optimum as a new individual chromosome for further evolution. The invention further relates to a method for intelligently switching the car systems of the blast furnace loading system. The problems that the car system scheduling mode of the blast furnace loading system is single, and the loading amount of a skip car cannot be optimal and cannot adapt to dynamically-changed loading tasks are solved.
