Based On The The Ecdis Ocean Routes Automatically Select The Optimal System Studies And Preliminary Implementation

This research aims at realizing the problem of the ocean route automatic selection and optimized in the ECDIS system. Considering there are many factors influence route design, and each factor has different influence on different ships, the research proposed a method on the basis of specific ship condition and sailing time to carry on the route selection, namely based on the establishment of route and climate database, in view of the specific ship condition, confirm routes' grade by means of fuzzy synthetic evaluation from the aspect of the security and the economy, select the most superior route accordingly. This research also considers the route optimization in navigating, according to possible avoids tropical storm and other obstacles situation in navigating, and proposes automatic route correction method to avoid tropical storm and other obstacles, and constructs ships avoidance network structure seeks the quickest route through the depth prior search method, thus achieves the route further optimization in the navigating.The research has realizing the route optimized selection system on the basis of establishing route and climate database and VC++ tool, and establish feasibility of the method through experiment that the same route has different grade to different type of ship by route evaluation.
