摘　　要：将排队论和元胞自动机相结合研究了单航道2上船舶进港时港口交通流的情况。当船舶进港时,将进港船舶和岸上的监控中心看作排队论的两个基本要素,采用数值模拟手段研究服务效率对整个船舶交通流的影响。数值结果表明:在无安全船距或较短服务时间的条件下,服务比率和平均通过率越大,船舶密度越小。Queuing theory and cellular automata were introduced to analyze port traffic stream in single channel. When ships enter into the port, the ship and the monitoring center are defined as two basic elements in queuing theory. Numerical simulation technology is used to analyze the effect of the serving efficiency on the vessel traffic flow. Numerical results showed that in the ease of no safety distance between two ships or shorter serving time, the serving officiency and the maximum ship pass rate is bigger and the vessel density is lower.
