| 摘 要： | 为获得内河航路交汇区域船舶通过能力,引入排队理论,研究船舶到达规律、排队机制、服务机制,建立基于单重休假规则M/G/1排队系统的交汇区域船舶通过能力研究模型,获得交汇区域船舶通过能力基本规律.分析结果表明:单艘船舶通过交汇区域所需时间越长,等候通过的船舶数量越多,船舶排队长度越长;当交汇区域船舶排队长度趋于无限长时,该处船舶通过能力仅由该区域服务能力决定.模型结果与实际数据比较证实了单重休假规则M/G/1排队系统模型的可用性及可靠性.

| Abstract: | To get the vessel transit capacity of inland cross area channel,an approach based on single vacation M/G/1 queuing theory was presented,and vessel arrival rule model,queuing rule and service rule model of cross area channel were studied.Simulation results show that the longer the time for one vessel passing through inland cross area channel,the more vessels have to wait to pass through cross area channel,and the longer the queuing length is.The vessel transit capacity of cross area channel only depends on t... |
