摘    要:在虚拟地理环境(virtual geographic environments,VGE)的研究中,城市公共安全作为一种典型的应用,致力于实现风险的认知与表达。然而,针对城市突发公共事件风险评估的共享管理需求与即时性需求,尚缺乏一种面向过程的风险监测与评估的表达方法,难以提供快速、全面的决策支持。针对此问题,本文首先基于元对象设施(meta object facility,MOF)建模架构,提出统一时空框架下面向过程的风险评估建模方法,实现风险监测评估方法的共享与重用,并提供面向过程的即时风险评估个性化信息服务。其次,设计了风险评估过程管理原型系统,实现风险评估过程建模、注册、执行和可视化等功能。最后,通过试验模拟太原市燃气泄漏事件作为应用案例,验证了方法的可行性。

关 键 词:面向过程  风险评估  风险监测  过程元模型  城市公共安全  信息服务

Abstract:Urban public safety is a typical application to realize the risk cognition and expression in the research of virtual geographical environment.However,for sharing management and instant demands of urban public emergencies risk assessment,there is a lack of process-oriented expression methods of risk monitoring and assessment to provide rapid and comprehensive decision support.Therefore,this paper aims at proposing a process-oriented risk assessment modeling method based on the MOF meta-model modeling framework under a unified space-time framework.The scheme can achieve sharing and reuse of risk monitoring and evaluation and provide instant,process-oriented personalized information services for risk assessment.It is also designed that a prototype system for risk assessment process management to realize the functions of risk assessment process modeling,registration,implementation and visualization.Experiment through the simulation of gas leakage in Taiyuan City as an application case verifies the feasibility of the method.
