Embodiment 1

[0050] Example 1, such as figure 1 As shown, applying a container loading method based on ant colony algorithm, the realization process of assembling a group of goods is as follows:

[0051] (1) Read the cargo data and cargo specifications in Table 1, and input the specifications of the container. Here, the load is infinite. It is determined that the center of gravity deviation rate of the cargo in the width direction after loading should not be greater than 5%, and in the length direction. The offset rate of the center of gravity should not be greater than 10%, the coincidence rate of the gravitational potential energy should be greater than 85%, and the maximum number of searches is MAX;

[0052] (2) Carry out code conversion for the goods to be loaded, convert the code selection problem to the path selection that can be handled by the ant colony algorithm, and initialize the path information;

[0053] Encode n goods P 1 , P 2 ,...,P n , and regard each node in the code ...

Abstract

The invention discloses a container loading method based on an ant colony algorithm. The method takes into consideration overall constraints such as the load capacity of a container, the stability of cargo placement, the convenience of loading and unloading and so on, and introduces the ant colony algorithm for a group of goods to be loaded in order to search for a stowage solution allowing for high space utilization rate. The specific proposal of the method is as follows: firstly, searching for the sequence of the goods to be loaded which allows the goods after being loaded to meet the constraints and get good space utilization rate; and secondly, loading goods according to the searched stowage solution allowing for high space utilization rate, wherein the stowage solution contains information on how goods to be placed. The container loading method of the invention has high use value.

Description

technical field [0001] The invention relates to cargo loading in the logistics transportation industry, more specifically, the invention relates to a container loading method based on an ant colony algorithm. Background technique [0002] The container is a modern tool in the long-distance transportation industry. It is a standardized and standard transportation container. The use of the container greatly improves the transportation efficiency. [0003] The space utilization rate of the container is one of the criteria to measure the quality of a loading effect. Since the container is used for transportation, the following aspects also need to be considered: the transportation carrier (such as a vehicle) has a load requirement, so the loading of the goods must be Weight restrictions; loading goods into the container will easily cause the overall center of gravity of the container to deviate from the center of the container. If the center of gravity of the container is seriou...
