Raw material scheduling method and device

Abstract

The invention provides a raw material scheduling method and device. The method comprises the steps that a raw material uncertain scheduling model is established; the raw material uncertain scheduling model is determined so that a determined constrained multi-target scheduling module is obtained; and the determined constrained multi-target scheduling module is solved so that raw material scheduling information is obtained, and raw material scheduling in the mixing process is performed according to the raw material scheduling information. The actual production process can be accurately described by establishing the raw material uncertain scheduling model, the raw material scheduling information of high accuracy can be obtained by a determined CMOSTA algorithm with variation, the raw material scheduling information has high performability, and raw material scheduling is performed according to the raw material scheduling information so that the production efficiency can be greatly enhanced and the product quality can be enhanced.

Description

technical field [0001] The invention relates to the technical field of material scheduling, in particular to a material scheduling method and device. Background technique [0002] At present, during the ironmaking process, the ironworks need to formulate a raw material scheduling plan according to the needs of the ironmaking mixing process, and schedule the ironmaking raw materials through the scheduling plan, so as to improve the ironmaking efficiency and ensure the quality of steel. [0003] At present, when formulating a raw material scheduling plan, technicians set up a stacking ratio plan according to the raw material planning indicators issued by the superior department, the total amount of each mineral raw material, and the constraints of the production process, and calculate each batching ratio based on past batching experience. The type of material used in the mixing stockpile and the corresponding proportioning ratio, so as to determine the batching plan of raw mat...

Problems solved by technology

[0004] Due to the many types of raw materials required in the ironmaking and mixing process, a lot of manual intervention is required to determine the scheduling plan of raw materials. When determining the batching plan of raw materials through the experience of technicians, the uncertainty of the incoming time cannot be considered. There is a large error between the ratio data of raw materials in the scheduling plan and the actual ironmaking ratio requirements, resulting in low production efficiency and poor quality of ironmaking
