Steelmaking and continuous casting scheduling method based on artificial bee colony (ABC)

Abstract

The invention discloses a steelmaking and continuous casting scheduling method based on an artificial bee colony (ABC). The method remains a framework of the ABC (comprising an employed bee phase, an observation bee phase and a scouter bee phase), and is improved by combining a JADE algorithm. At the employed bee phase, a search strategy of the JADE is used for updating individuals in one population, and the diversity of the population can be increased by adopting an external archiving mechanism of the JADE; at the observation bee phase, updating operation of differential solution, and archiving composed of the current population is increased on the basis of a previous search strategy of the ABC; and at the scouter bee phase, the previous search strategy of the ABC at the phase is adopted. With the adoption of the method, the convergence of the population is accelerated under the condition of guaranteeing the diversity of the population, and an ideal scheduling result can be generated in relatively short time, so that the aims that the waiting time of workpieces in a steelmaking and continuous casting process and the machining cost is reduced are realized.

Description

technical field [0001] The invention belongs to the field of job scheduling in the steelmaking and continuous casting process, in particular to a steelmaking and continuous casting scheduling method based on an artificial bee colony algorithm. Background technique [0002] The steel industry is a fundamental industry for many other industries such as construction, automation, etc., and occupies an important position in the world economy. The steelmaking process (Steelmaking Process) refers to the process of smelting iron with a fixed ratio of chemical components into steel and then solidifying into steel plates in a high-temperature environment. It can effectively help steel plants produce steel plates. The steelmaking process is roughly divided into three stages: ironmaking, steelmaking and continuous casting, and hot rolling. Among them, the steelmaking and continuous casting stage plays a connecting role in the entire steel production process and is a key link in the stee...

Problems solved by technology

[0007] (4) For the workpiece processed in the refining and continuous casting stage, when there is no available machine, it must wait until there is an available machine, which will cause the temperature of the waiting workpiece to drop, and will generate the cost of reheating the workpiece;

[0010] (7) There is still a transfer time between the two processing stages of the workpiece, but due to the huge capacity, the configuration of the intermediate transport crane is ignored;

However, the existing methods for steelmaking and continuous casting scheduling cannot achieve ideal scheduling results in a short period of time
