中文摘要：

为合理确定海港进港航道设计的基本尺度,建立海港进港航道设计辅助分析系统,为设计人员提供港口服务水平、船舶等待时间等信息。充分利用网络、计算机仿真等技术,实现船舶航行作业系统仿真、影响因素分析等功能,并给出系统总体结构及类结构。应用实例表明该系统能模拟船舶航行作业过程,可有效协助设计人员优化航道设计方案。

英文摘要：

To determine the dimension of coastal entrance channel,this paper develops a computer aided analysis system（CAAS） for supplying valuable information such as port service level,waiting time and so on.Integrating the network technology with computer simulation,this paper presents the structures of the system and classes,and achieves the functions of ship navigation simulation and influence factor analysis.An application proves that the CAAS performs well and is helpful for optimizing the dimension of coastal entrance channel effectively.
