Embodiment Construction

[0098] The specific embodiment of the present invention includes the following seventeen steps:

[0099] Step 1: Determine what you want to achieve:

[0100]

[0101] This goal mainly considers two aspects: the minimum sum of the horizontal distances of all containers in the port from the yard container area to the berth of the corresponding ship, and the total delay of the ship caused by the failure of all ships at the container terminal to leave the port before the planned departure time. Minimum time. Among them, the variables of formula (1)-(40) are as follows: l sv is the transportation distance of the container; is the number of containers allocated to the sub-container area s by the ship v in the w scenario; TD v is the total delayed departure time of ship v; R is the set of yard lanes; B is the set of container areas; V is the set of arriving ships; W is the scene set of all sub-container changes in the whole planning cycle; SB is the set of all sub-containers ...

Abstract

The invention discloses a container port storage yard template optimization method considering ship operation time requirements. According to the method, the time factor of container ship in-port operation is considered, the optimization problem of storage yard sub-container area distribution (storage yard template plan) is researched, and a storage yard template plan mathematical model integrating a container area sharing strategy and ship delayed departure punishment is established, so that the number of container distribution points of ships in a storage yard is determined, and sub-container area distribution is optimized. And solving by utilizing a designed heuristic algorithm (genetic algorithm) solving model and a CPLEX solving solver. Through example research, the effectiveness of the model and the excellence of the design algorithm performance are verified. And through sensitivity analysis, the influence of the change of the field bridge operation efficiency and the change of the box area sharing coefficient on the result is explored.

Description

technical field [0001] The invention relates to container area allocation in port container yard, in particular to a container port yard template optimization method considering ship operation time requirements. Background technique [0002] At present, the operation efficiency and production capacity of container port yards have become the key to port operations. The management level of yard space resources will directly affect the service quality of the container terminal, and then affect the development of the core competitiveness of the entire container port. The existing research on the allocation of container areas at the tactical level is relatively weak. The main purpose is to minimize the storage space to meet the storage requirements of container ships, and to improve the utilization rate of the storage yard space as much as possible to meet the storage challenges faced by the port. Alleviate the conflict between yard space resources and land resources. Few liter...
