Abstract

The invention relates to a multi-crown-block scheduling optimization method and system, and the method comprises the steps: building a multi-crown-block dynamic scheduling model through the matching of a task and crown blocks, calculating by a double-tangent-point cross genetic algorithm based on real number coding, obtaining an optimal driving scheme of multiple crown blocks in a steelmaking refining continuous casting production process, effectively reducing the invalid number of times of giving way to the crown blocks, and improving the efficiency. The effective operation rate of crown block driving is improved. The model, the algorithm and the rule provided by the invention have the advantages of strong universality, high convergence speed, balance of crown block workload and the like,and have great reference value for improving the crown block operation efficiency, shortening the molten steel waiting time of a station and the like.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a scheduling optimization method and system for multiple cranes in the production process of steelmaking-refining-continuous casting. Background technique [0002] The steelmaking-refining-continuous casting production process is in the upstream of the production process of steel products and is a key link in the production of steel products. Among them, the crane has the advantages of large lifting capacity, relatively stable operation, and does not occupy ground space. It is the main transportation tool for the turnover of ladles in steelmaking workshops between various processes. Reasonable and effective scheduling of cranes will help to improve the hoisting of steel ladles between steelmaking-refining-continuous casting processes, ensure continuous casting of continuous casting machines, lay the foundation for the implementation of upper-level production scheduling and i...
