针对提高高速铁路应急救援的效率，保证高速铁路应急预案实施流程的可操作性，更好地利用信息技术支持应急响应过程，介绍了运用软件开发中的场景驱动概念以建立高速铁路应急预案流程控制工作流模型的新方法.该方法是一种结构化的方法，强调场景在整个流程控制中的作用, 并以此为核心驱动工作流模型的设计.在不同的抽象层次上使用可视化标记语言UCM对场景模型进行描述，通过对模型分层细化、逐步扩展的方式以达到结构清晰、信息完备的效果.在此基础上针对UCM的结构特点设计了具体的流程控制算法，对整体的应急响应过程的执行细节进行成效分析和逐步优化.最后结合实例阐述本方法如何使用.

Scenario-driven Approach of High Speed Railway Emergency Plan Process Control

Aiming at improving the efficiency of high speed railway rescue work and ensuring the maneuverability of high speed railway emergency plan implementation,supporting emergency response with a better use of information technology,this paper introduces a structured method of constructing high speed railway emergency plan process control workflow model using the notion of scenario-driven in software development.The method emphasizes the function of scenario which drives the designing of workflow model in the whole process control.Then it describes a graphical notation UCM at different level of Abstraction,which can be gradually extended and hierarchically refined and thus expected to achieve a clear structure and information completeness effect.In addition,it designs a concrete process control algorithm based on the feature of UCM structure which analyzes and optimizes the operation details of the whole emergency response.The paper finally discusses how to use the method with an example.
