Vehicle part loading method and system

Abstract

The invention discloses a vehicle part loading method and system, and relates to the technical field of vehicle loading layout optimization. The vehicle part loading method comprises the steps of constructing a loading block, and generating a loading scheme and an optimized loading scheme, during a gravity adjustment process, judging whether the remaining loading blocks can be loaded into a carriage one by one according to the loading sequence, if the remaining loading blocks cannot be loaded in the carriage, calculating the center of gravity of the carriage under the current pattern and judging whether the center of gravity meets the center-of-gravity constraint, and when the gravity center constraint is not met, taking out the loaded loading block to be adjusted to meet the gravity center constraint, updating the loading scheme, and calculating the loading rate corresponding to the loading scheme. 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 a 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, in particular to a loading method and system for vehicle components. Background technique [0002] The three-dimensional loading problem is one of the key research issues in the logistics industry. It refers to loading the goods into a container with the optimal space utilization rate according to the requirements of the weight of the goods, while ensuring that the goods are stable, undamaged, and not overloaded. Load balance, in order to achieve the purpose of reducing transportation costs and improving economic efficiency. The three-dimensional box packing problem is a geometric combinatorial optimization problem. Although the shape of the goods is irregular, the goods are usually packed into the outer packing box of the cuboid in the industry, so this problem can be regarded as the combinatorial optimization of the cuboid shape goods. The 3D bin packing problem inv...

Problems solved by technology

[0008] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a method and system for loading vehicle components. The present invention considers the limitation of the center of gravity of the carriage when the vehicle is loaded, and treats the center of gravity of the carriage as the constraint condition of the loading problem. The loading scheme that satisfies the constraint of the center of gravity is adjusted through the backtracking algorithm until a feasible loading scheme is generated; furthermore, the stacking rules are treated as the constraints of the loading problem
