An optimization method for overturning and placing containers in container yards under the condition of incomplete pick-up information

Abstract

The invention discloses a container yard turnover falling optimization method under incomplete container picking information. The method comprises the following steps of performing simulation learningon a designed Q value table by utilizing container yard container picking operation simulation to obtain a Q value table after simulation learning; and step 2, dynamically generating an action instruction of the container turnover falling by utilizing the Q value table after learning and an action selection strategy, selecting a container falling position of a container to be turned over according to the action instruction, and adaptively updating the Q value table according to execution feedback of the action instruction in the yard container picking operation process. By adopting the method, self-adaptive adjustment of a container turnover falling optimization instruction in the yard container overturning operation environment can be realized through Q value learning in the container picking process; and the learning and convergence speed of a Q algorithm is increased, and the container turnover rate of a multi-layer stacking container yard and the secondary container overturning rate of the container yard are lowered.

Description

technical field

[0001] The invention belongs to the technical field of automobiles and transportation, and specifically relates to an optimal method for overturning and placing containers in a container yard under incomplete container pick-up information. Background technique

[0002] 90% of the freight volume of international trade is completed by sea through the port. Container transportation has the advantages of safety, efficiency, and ease of automation. It has developed rapidly since it appeared in the 1950s and has become the main form of shipping. With the development of economic international trade and the continuous growth of container freight volume, container terminals and yards are required to have greater throughput capacity, higher operating efficiency and more economical operating costs. The optimization of container turnover rate in the yard is one of the keys for container terminals and yards to improve throughput capacity and operating efficiency, and red...
