Collaborative Optimization of Gate Lane and Yard Crane Configuration Considering Dual Transaction Trucks Priority
Dual transaction external container trucks deliver one container and pick up another in a single trip,increasing the efficiency of terminal collection and distribution,and thus should be given higher priority.In order to investigate the effect of prioritizing dual transactions trucks on gate lane and yard crane configuration,the dual transactions truck priority channel is introduced at the gate,and a three-level priority queuing system is established in the yard.The three-level queuing system prioritizes internal truck operations,followed by dual transactions external trucks and then single transaction external trucks.The queuing model for trucks at the terminal gate and in the yard is formulated.Based on the queuing model,a bi-objective mixed-integer programming model is developed,with the objective of minimizing the number of gate lanes activated and yard cranes configured and minimizing the number of external container trucks queuing.A multi-objective evolutionary algorithm based on decomposition,with pointwise stationary fluid flow approximation,is proposed.Numerical analysis demonstrates the effectiveness of the method.For the same terminal resource configuration,the average number of dual transaction trucks queuing at the gates and at the yard is decreased by 21.82%and 18.27%after considering the priority of dual transaction trucks.
