Design and implemention of coastal entrance channel design computer aided analysis system

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.
