Design of Large Scale Facilities with Open Finite Queueing Networks

对复杂的大型设施(如制造和组装厂、医院、机场和其他建筑类型)进行建模是一项艰巨的任务，因为混合交通流的数量和复杂性很大，有限资源的争用以及解析求解该模型表示的相应困难。一种称为广义扩展法的新技术将被开发用于大型复杂设施的设计和建模，该方法模拟具有一般服务时间、有限等待空间和多类(链)客户类型的开放有限排队网络。最近发展了一种解析的状态相关流模型，用于捕获建筑物循环系统内的客户和居住者的运动作为循环系统中拥堵的函数。这项研究的主要目标是将这些状态相关流动模型与广义扩展方法相结合，以便对大规模设施规划和设计问题进行建模。由于网络的复杂性、网络中的大量服务器以及由此产生的业务流的混合和叠加，诸如广义展开法之类的技术是对大规模设施进行分析建模的非常有效和强大的工具。

Modelling complex large facilities such as manufacturing and assembly plants, hospitals, airports, and other building types is a difficult task because of the great volume and complexity of mixing traffic streams, the contention for finite resources, and the corresponding difficulty of analytically solving this model representation. A new technique, called the Generalized Expansion method, which models open finite queuing networks with general service times, finite waiting room, and multiple classes (chains) of customer types will be developed for the design and modelling of large complex facilities. Analytic state dependent flow models for capturing customer and occupant movement within the circulation system of building as a function of congestion in the circulation system has been recently developed. The main goal of this research is to integrate these state dependent flow models with the Generalized Expansion methodology in order to model large scale facility planning and design problems. Techniques such as the Generalized Expansion method are very effective and powerful tools for analytically modelling large scale facilities as queuing networks because of the complexity of the network, the large number of servers within the network, and the resultant mixing and superposition of traffic streams.
