Abstract

The invention discloses a method and a system for optimizing loading layout of three-dimensional containers, wherein the method comprises finding a group of rough feasible solutions in a solution space by utilizing the random rapid searching capacity, potential parallelism and global convergence of a genetic algorithm, then using the group of rough feasible solutions as the inputs of an ant colony algorithm, and obtaining the optimal loading solution by the positive feedback mechanism, parallelism and capacity of searching better solutions of the ant colony algorithm, thereby realizing the fusion of the genetic algorithm and the ant colony algorithm in the solution to the loading layout problem of containers; the method avoids the defects of solving the loading layout problem of three-dimensional containers by a single algorithm at present, gives consideration to a plurality of important constraint conditions influencing the loading efficiency while considering global search capability, and has a good applicability.

Description

technical field [0001] The invention belongs to the field of container loading layout optimization design, in particular to a method and system for optimizing a three-dimensional container loading layout. Background technique [0002] The three-dimensional container loading layout optimization method refers to loading a batch of goods into the container according to the appropriate loading method under certain constraints, so as to maximize the volume utilization rate or loading quality utilization rate of the container, so as to realize reasonable and effective container loading. Using the method, its objective function can be expressed as: max Z = λ ( Σ i = 1 n l i · w i · h i ...
