英文摘要：

The concise and effective decision support system of ship intelligent collision avoidance is the key for ship safety running, is also one of difficulties on the research of international marine intelligent transportation system. Based on the hardware system construction of AIS ship monitoring network, we deeply discuss the key technologies on ship collision avoidance in this paper. Some advanced information technologies including muhisource information fusion and practical system construction idea are used to present a concise and effective decision support system scheme of ship intelligent collision avoidance（IDSSVCA）. Firstly, the current status about the decision support sys- tem of ship intelligent collision avoidance is analyzed and the main problems are summarized. Afterwards, the re search and development scheme is given. Synchronously, the key issues which should be solved are presented and the scheme analysis is also given.
