Simulation-based performance evaluation of container yard with twin yard cranes

以双场桥集装箱堆场为研究对象,通过建立堆场作业多智能体仿真模型,研究接力作业模式下堆场的作业效率和能耗。模拟在自动导引车和港外集卡抵达时间不确定性的条件下双场桥复杂的作业过程,实现堆场机械功率和能耗的定量计算。通过对作业效率和能耗指标的定量分析,探究不同工况下接力区位置对堆场效率和设备能耗的影响。结果表明:堆场作业仿真模型可有效模拟堆场设备作业流程及其交互行为,并得到不同工况下的效率和能耗指标值。此外,最大效率和最小能耗对应的接力区位置不尽相同,应根据具体工况合理设计接力区来实现效率和能耗的双目标。

This study takes the container yard with twin automated yard cranes as the research object.A multi-agent-based simulation model of yard operation is established to study the efficiency and energy consumption of yard with relay mode.The model simulates the complex operation process of twin yard cranes under the uncertainty of arrival time of automatic guided vehicles and external trucks,and realizes the quantitative calculation of power and energy consumption of yard machinery.Through the quantitative analysis of the indexes of efficiency and energy consumption,the influence of the handshake area location on the yard efficiency and machinery energy consumption for different working conditions is explored.The results show that the yard operation simulation model can effectively simulate the operation process and interaction behavior of yard equipment,and obtain the index values of efficiency and energy consumption for different working conditions.In addition,the handshake area location corresponding to the maximum efficiency and minimum energy consumption are different,and the handshake area should be reasonably designed according to the specific working conditions to achieve the dual goals of efficiency and energy consumption.
