Various approaches have been used to identify possible routes for improvement of patient flow within an emergency unit (EU). One such approach is to use simulation to create a 'real world' model of an EU and carry out various tests to gauge ways of improvement. This paper proposes a novel approach in which simulation is used to create a 'perfect world model'. The EU at a major UK hospital is modelled not as it is, but as it could be. The 'efficiency gap' between the 'perfect world' and the 'real world' demonstrates how operational research can be used effectively to identify the location of bottlenecks in the current 'whole hospital' patient pathway and can be used in the planning and managing of hospital resources to ensure the most effective use of those resources.
已经采用了各种方法来确定在急诊部门（EU）内改善患者流程的可能途径。其中一种方法是使用模拟来创建 EU 的“真实世界”模型，并进行各种测试以衡量改进的方法。本文提出了一种新颖的方法，即使用模拟来创建“完美世界模型”。对英国一家大医院的 EU 的建模不是按照其实际情况进行，而是按照其可能的情况进行。“完美世界”和“真实世界”之间的“效率差距”表明了如何有效地利用运筹学来确定当前“整个医院”患者路径中的瓶颈位置，并可以用于规划和管理医院资源，以确保最有效地利用这些资源。
