Abstract

The present invention relates to the technical field of yard and bridge scheduling, and discloses a yard and bridge scheduling optimization method, device and computer storage medium with double spreaders, including the following steps: considering the synergy between double spreaders when performing the same bay position task, calculating the field The completion time of the bridge loading and unloading operation, using the completion time of the yard and bridge loading and unloading operations as the objective function; setting the constraints of the yard and bridge operations, the constraints include storage location constraints, task category constraints, and collection truck stop constraints for job tasks; Taking the minimum completion time of yard and bridge loading and unloading operations as the goal, and under the constraints, an optimization model of double spreader yard and bridge scheduling is established; the genetic simulated annealing algorithm is used to solve the optimization model of double spreader yard and bridge scheduling, and the optimal Yoshiba Bridge executes the task sequence. The dispatching optimization method for yard and bridge with double spreaders provided by the present invention fully considers the characteristics of double spreaders, maximizes the advantages of double spreaders, and shortens the task execution time.

Description

technical field [0001] The present invention relates to the technical field of yard and bridge dispatching, in particular to a method, device and computer storage medium for optimizing yard and bridge dispatching with double spreaders. Background technique [0002] The operation scale and business level of container terminals at home and abroad are in a continuous development trend with economic growth, and the storage yard, as an important bridge connecting the front of the terminal and the gate, is a transfer station for container transportation on both sides of the sea and land of the automated terminal. Its loading and unloading efficiency plays a vital role in the overall operation level of the terminal. The loading and unloading operations in the yard are mainly completed by automatic stacking cranes (referred to as yard bridges). Due to the increase in container throughput, the original equipment and resources are gradually unable to meet the needs of production. Ther...
