Automatic batch grouping method for automobile transportation material sampling in bulk cargo yard

Abstract

The embodiment of the invention discloses an automatic batch grouping method for automobile transportation material sampling in a bulk cargo yard. The method comprises steps that a forced batch grouping task and a conventional batch grouping task are created according to the relation between the total transportation mass of vehicles which are not grouped and the forced batch grouping mass and thetarget batch grouping mass respectively; for any group batch task, if the current moment is greater than the group batch execution moment corresponding to the group batch task, a group batch identifier is obtained corresponding to the group batch task; if the grouping identifier is forced grouping, the vehicles with the same order number are grouped in the grouping task, and if the grouping task identifier is conventional grouping, the vehicles with the same order number in the grouping task are conventionally grouped; and after batch grouping, the data are added into a group batch set. According to the method, the optimal vehicle combination can be obtained, so inspection and test cost is saved, and meanwhile, the forced grouping quality is set for the vehicles with insufficient vehicle transportation quality and target quality, so the situation that the vehicles wait for grouping for a long time in a parking lot is avoided.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular relates to an automatic batching method for sampling and batching materials transported by automobiles in bulk cargo yards. Background technique [0002] Iron and steel production requires a variety of raw materials, such as iron ore powder, ferroalloy, fuel and various auxiliary materials, etc. 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 iron and steel enterprises purchase raw materials and fuels, they will conduct batch sampling of logistics vehicles entering the factory, and there are strict regulations 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 kilogram of samples according to the batc...

Problems solved by technology

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