摘　　要：基于进出港口的船舶自动识别系统(Automatic Identifcation System,AIS)数据,综合船舶时空位置信息及码头装卸货信息,针对港口船舶营运效率评估,提出船舶在港时间、船舶泊位停留时间、泊位有效占有率、船货集疏运通行能力、码头吞吐量和船舶NO_x排放量等港口船舶营运效率指标,重点描述港口船舶营运效率评估系统的总体结构、总体功能和实现方法。The operational efficiency of ships in ports directly affect the cost of cargo transportation and the shipping company＇s operation efficiency. This paper introduces a set of indices for evaluating the operational efficiency of ships in a port is troduced based on the information extracted from Automatic Identifcation System（ AIS） data,such as the time period of ship staying in a port,berth occupation time,cargo type and tonnage and other information. The efficiency indices include the time in port,the time at berth,effective berth occupation,cargo tonnage and some others. The overall structural design,overall function design,and the implementation of the evaluation system are described.
