Problems solved by technology

[0004] Due to the lack of consideration of the center of gravity of the car and the stacking rules of the cargo box, the generated cargo loading plan is often difficult to reach the theoretical value when the actual vehicle is loaded

Embodiment

[0082] A method for adjusting cargo loading, comprising the steps of:

[0083] S100. Load multiple goods to be loaded, and the goods cannot be stacked on top of each other in height.

[0084] The goods described in this embodiment are the loading units after the stacking operation is carried out by using the stacking method, and the height of the loading units (goods) can no longer be stacked, so that the three-dimensional loading problem can be reduced to a two-dimensional loading problem .

[0085] In particular, considering that some cargo boxes need to be placed on pallets during actual operation, it also includes a step of stacking the objects to be packed on pallets in multiple layers to form a pallet unit. One pallet unit counts as one shipment. When stacking multiple layers, the height of the carriage is used as the stacking height threshold, that is, the overall height of the pallet unit is not greater than the height of the carriage.

[0086] The boxes on the pall...

Abstract

The invention discloses a cargo loading adjustment method and device, and relates to the technical field of vehicle loading layout optimization. The cargo loading adjusting method comprises the stepsof loading a plurality of cargos to be loaded, wherein the cargos cannot be mutually stacked in the height direction; according to a preset constraint condition, judging whether the unloaded goods canbe loaded into the carriage or not; when it is judged that the unloaded cargos cannot be loaded into the carriage, generating a loading scheme, calculating the carriage gravity center position underthe loading scheme, judging whether the gravity center position meets gravity center constraints or not, wherein the gravity center constraints comprise the x-axis, y-axis and z-axis requirement ranges; and when it is judged that the gravity center constraint is not met, performing gravity center adjustment by using a backtracking algorithm. According to the method, the gravity center of the loading scheme which does not meet the gravity center constraint is adjusted through the backtracking algorithm until the feasible loading scheme is generated, so that the accuracy of the vehicle loading plan is remarkably improved, and the vehicle loading plan is closer to the actual operation.

Description

technical field [0001] The invention relates to the technical field of vehicle loading layout optimization. Background technique [0002] The three-dimensional loading problem is a geometric combinatorial optimization problem, which is usually regarded as the combinatorial optimization of cuboid-shaped cargo. Specifically, the three-dimensional loading problem is to determine a feasible loading scheme for a given truck to be loaded and a batch of goods to be loaded so that the vehicle loading rate is maximized under basic constraints. This problem needs to meet four assumptions: 1) the compartment and the goods to be loaded are both cuboids; 2) the goods placed must be completely contained in the compartment; 3) the goods can only be parallel or perpendicular to the edges of the compartment 4) It is required that the goods can only be rotated around the height edge, and cannot be dumped. The common constraint conditions include the constraint that the goods are not embedde...
