Embodiment Construction

[0031] The control method for deploying container yard trailers in the container terminal of the present invention will be described in conjunction with the accompanying drawings and embodiments.

[0032] This method provides a trailer allocation decision system oriented to the whole terminal, rather than an operation line allocation, that is, all trailers can dynamically serve all quay cranes, rather than fixedly assigning specific trailers to a certain quay crane. Then an integer programming model is developed based on the deployment method to solve the practical problem. The objective function of this model is subject to the following two conditions, namely, the minimization of the total transportation time and the minimization of the total transportation energy consumption. In view of the reasonable range of values ​​for the calculation of the problem, the present invention applies a heuristic algorithm based on the Hungarian algorithm. In addition, considering the dynamic...

Abstract

The invention provides a control method for allocating yard trailers of a container terminal. The control method is an allocation method conforming to the integral terminal instead of being only specific to a certain operational level of the terminal. The allocation method is implemented in an allocation decision making system for the yard trailers of the container terminal, and the allocation arrangement which is implemented by the control method for all the trailers dynamically serves all shore bridges. The control method has the advantages that as tests by the control method show, running distances of the yard trailers in non-working states are shortened, idle periods of shore cranes and yard bridges are shortened, the quantity of the trailers is reduced, the productivity of the container terminal can be effectively improved owing to the allocation arrangement for the yard trailers, and energy consumption is reduced. Besides, the average task completion time and the total transportation energy consumption of container trucks are smaller than actual values, and minimum decrement rates of the average task completion time and the total transportation energy consumption are 12.7% and 13.6% respectively.

Description

technical field [0001] The invention relates to a control method for allocating trailers in container wharf yards. Background technique [0002] As one of the most important transportation equipment between the container terminal yard and the front of the terminal, the yard trailer plays a key role in the terminal's production capacity and energy consumption. Quayside load bridges and yard cranes may need to wait for the arrival of trailers if the deployment of trailers is not reasonable. Therefore, it is very necessary to use a reasonable allocation of yard trailers to ensure the smooth operation of loading and unloading bridges and yard cranes. [0003] With the growing importance of container terminals in global trade, more and more scholars pay attention to the research on terminal operations. For example, Yin et al. [1] (2011) proposed a distributed intelligent system for the deployment problem of dynamic harbor plans. Kim and Park [2] (2004) established a mathemat...
