Description

technical field [0001] The invention belongs to the technical field of steelmaking-continuous casting, and in particular relates to a scheduling system and method for steelmaking-continuous casting production. Background technique [0002] The steelmaking-continuous casting production process is the core link in the production process of modern iron and steel enterprises, including three major processes: converter smelting, refining furnace refining and continuous casting machine casting. Steelmaking-continuous casting production scheduling is based on the pouring schedule. Under the known conditions of the production process path of the furnace and the continuous casting machine that the furnace is cast in the continuous casting process, the pouring is started on the continuous casting machine on time. Continuous casting of heats within a pouring time, two adjacent heats processed by the same equipment can not cause operation conflicts as the scheduling goal, determine whic...

Problems solved by technology

[0003] At present, the testing of the steelmaking-continuous casting production scheduling algorithm is mainly divided into three categories: the first category is the offline testing of the steelmaking-continuous casting production scheduling algorithm, which is only a test of the algorithm function, that is, according Input data to verify whether the correct planning and scheduling results can be obtained after algorithm processing (such as unit testing, integration testing, system testing, etc.), and does not test and analyze the advantages and disadvantages of the algorithm

The second type of situation is to conduct an online test on the steelmaking-continuous casting production scheduling algorithm in the actual production process, and send the scheduling result obtained after the scheduling algorithm to form an instruction to the production process to verify whether the planned scheduling result can correctly guide the production. This method does not test and analyze the advantages and disadvantages of the algorithm, but only verifies whether the scheduling results are applicable to the actual production process. At the same time, the long online test time also affects the actual application of the scheduling algorithm.

The third type of situation is the simulation test of the scheduling algorithm for steelmaking-continuous casting production. This type of research is mainly to test and verify the pros and cons of the scheduling algorithm, but these methods do not compare the scheduling algorithm with the actual production process (or close to the actual production process). The production process) is connected to carry out online testing, so that there are still many problems in the actual application process of the studied algorithm, which leads to the fact that the algorithm cannot be really well applied in practice.

To sum up, it can be seen that the steelmaking-continuous casting production scheduling algorithm has not been tested in the actual production process (or close to the actual production process) environment, so that the researched Steelmaking-continuous casting production scheduling algorithm is difficult to effectively guide the actual production process
