【摘要】 船上淋浴系统设计的合理性作为全船设计初始的一个重要环节,目前,国内外人士均未提出一种有效的方法对此进行验证评估。因此,针对船上淋浴系统设计方案合理性的研究,具有广泛的实际应用价值。本文利用离散事件系统仿真手段对游船实际的淋浴系统进行研究,首先根据实际的船上淋浴系统的物理模型抽象出具有普遍意义的通用模型,然后以乘客实体为主线建立了整个淋浴系统运行的实体流程图。同时应用排队理论分析了淋浴系统淋浴头的平均利用率,找到影响系统淋浴能力的各种因素,并利用泊松分布来描述乘客的随机到达过程。结合实际情况简化淋浴系统的理论模型,借助图论中最短路径的Floyd算法对淋浴路线进行规划,然后基于事件调度的仿真策略设计淋浴系统的仿真模型,并利用UML建立淋浴系统的仿真模型框架,划分了淋浴系统的功能模块,采用面向对象的思想设计了淋浴系统实体类,编写了用于评价船上淋浴系统合理性的仿真程序。本文最后利用专业仿真软件QUEST对淋浴系统进行仿真。建立了QUEST中淋浴系统的仿真模型,模拟了不同纯淋浴时间下的仿真方案,分析仿真结果,验证了淋浴系统的淋浴能力。更多还原

【Abstract】 The design of shower system in large ship holds an important role. However, there is no effective way to validate the rationality of the design both abroad and home. Therefore the research for the rationality of shower system design takes on a practical value.The actual shower system of a ship is researched by use of discrete event system theories and methods for simulation. At first, according to the physical model of the shower system, the general model having a prevalent meaning has been built in the abstract. In virtue of the queue theory, the paper analyzes the shower utilization in order to find the effect factors and describes the stochastic arrival process of the crew. Then mathematics model of the shower system problem has been made with entity flow chart. In the paper, According as the actual shower instance, the mathematics model has been predigested, such as the area partition of the whole ship, the layout of shower route by using floyd arithmetic and so on. Basing on predigesting the mathematics model, the paper adopts the event scheduling as the simulation strategy and has built the simulation model of the shower system using UML. In addition, the paper has made use of the 00 idea to design the entities class.Finally the paper has solved the problem of shower system by using of another way of the professional simulation software namely QUEST. In QUEST, the simulation model of shower system has been made and different simulation projects have been applied. The results of simulation have validated the original design of shower system.更多还原
