A Process-oriented Risk Monitoring and Assessment Modeling Approach in Urban Public Safety

doi:10.11947/j.AGCS.2018.20180117

Abstract

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.

Key words: process-oriented, risk assessment, risk monitoring, process meta-model, urban public safety, information service
