A multi-objective optimization-based method for automobile sampling and batch grouping in iron and steel enterprises

Abstract

The embodiment of the present invention discloses a multi-objective optimization-based method for automobile sampling and group batching in iron and steel enterprises. The method includes: for all transport vehicles to be grouped and batched, acquiring the arrival information of each transport vehicle, and selecting the vehicle according to a preset method. The batch cycle performs batch operations periodically. The group batch operation includes: if there is a group batch corresponding to the order number to be grouped in the group batch set, the vehicles that meet the preset conditions are added to the corresponding group batch in turn. If the total transportation quality of the vehicle collection is greater than or If it is equal to the target batch quality, the batch will be grouped according to multi-objective optimization. If there are vehicles with a waiting time greater than the maximum batch waiting time, all vehicles in the vehicle set will be grouped into one batch and added to the batch set until all order numbers are processed. Finish. Comprehensive batch grouping is carried out according to multi-objective optimization and the maximum batching waiting time, so as to realize the double optimization of the batching quality and the average waiting time of the batching vehicles, saving the cost of inspection and testing, and taking into account the waiting cost.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular relates to a multi-objective optimization-based method for automobile sampling and batch grouping in iron and steel enterprises. Background technique [0002] Steel production requires a variety of raw materials, such as iron ore powder, ferroalloys, fuels and various auxiliary materials. The quality of these raw materials is not only an important basis for formulating smelting production process parameters, but also determines the settlement price of materials. When purchasing raw fuels, iron and steel enterprises will conduct batch sampling for the logistics vehicles entering the factory, and have strict specifications on the sampling process. The purpose of batching is to obtain a sample that is reasonably representative of the overall quality. In production, iron and steel enterprises often obtain a certain amount of samples according to the batch weight specified by t...

AI Technical Summary

Problems solved by technology

At present, domestic iron and steel enterprises generally rely on dispatchers to organize batches based on their experience in the batch scheduling of vehicles purchased from abroad. There are unscientific batch organizations that lead to high testing costs and irregular operations such as "human batches", which affect the use of enterprises. material cost
