调查大连港集装箱码头连续3年10 280个航班的到港时间记录,分析集装箱班轮实际到港时间与船期的偏差规律,证明集装箱班轮晚班到港概率服从伽马分布,并提出利用该特性优化泊位计划的思路和方法.以大连港为案例,对泊位计划进行优化,结果可使泊位前后航班时间间隔损失平均减少5.58 h,航班靠泊发生冲突概率平均减少9.47%.实例证明了该方法的有效性和实用性.
To investigate the arrival time records of Dalian Port Container Terminals for 10 280 consecutive 3-year flights for 3 years and analyze the deviation rule between the actual arrival time of the container ships and the shipping schedules, and to prove that the probability of late arrival arrivals of container ships is subject to the gamma distribution and propose to utilize this characteristic Optimization of berth planning ideas and methods.Optimization of berth planning with Dalian Port as an example, the results can reduce the flight time interval loss before and after the berth an average of 5.58 h, the probability of collision berthing flight average reduction of 9.47% Effectiveness and practicality.
