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.
