A Simulation Model to Determine the Capacity of a Y-type Wat

论文使用Arena软件进行复杂系统的仿真,包括交通规则、潮汐窗口、天气条件和不同船型等。以盘锦港为案例,研究了船舶航速为10节时Y型航道的通过能力。除此之外,在船舶航速为11节时,取潮位累积频率80%,下沉值仍然满足船舶的安全航行要求。研究表明,在船舶航速为11节时,由于船舶等待潮位的时间增加,与潮位累计频率90%时相比,航道的通过能力有所减小。评估港口服务水平是港口管理机构的最重要的目标之一。通常使用船舶平均等待时间与船舶平均服务时间的比值来评估港口的效率。由于港口运营的随机性,Arena软件可用于仿真复杂的港口系统。本篇论文以主航道为研究对象,该航道同时拥有东、西两条分支。通过对盘锦港进行一年的仿真研究,作者计算了每种船舶类型的平均等待时间与平均服务时间的比值。结果表明,10万吨级油船对航行水位的要求较高,其等待潮位的时间较长,而其它货种的船舶的等待时间都在可接受范围内。随后,重新构建模型研究了不乘潮进港的可能性,以及此时船舶的平均等待时间与平均服务时间的比值。结果表明,平均等待时间与平均服务时间的比值有所减小。对于本研究中的其它船型,没有因交通条件或泊位不足而导致的延误,盘锦港的...
