高校实验室安全风险管理系统动力学仿真与应用

Simulation and application of university laboratory safety risk management system dynamics

采用系统动力学(system dynamics,SD)建模理论,将实验室安全风险管理视为一个系统,以实验管理相关人员、环境、设备设施及管理作为子系统,解析子系统的多异质风险因素,构建实验室安全风险管理SD模型,并以某高校矿山与地下工程测量实验室为例进行演化模拟与仿真验证。结果表明,SD模型可以动态模拟实验室安全管理水平演变态势,通过调控对应子系统的安全投入占比可甄别最优投入方案,求解出各子系统对实验室安全风险管理总水平的实际贡献率,进而重点防范和管控子系统的风险因素,可为高校精准识别实验室安全投入方向和制定管理决策提供新路径。

SD modeling theory is adopted to treat laboratory safety risk management as a system.The relevant personnel,environment,equipment and facilities and management are taken as subsystems to analyze the multiple heterogeneous risk factors of the subsystem and establish SD model of laboratory safety risk management.By taking the survey laboratory of mine and underground engineering in a university as an example,the evolution simulation and simulation verification are carried out.The results show that SD(system dynamics)model can dynamically simulate the evolution trend of laboratory safety management level.By adjusting the proportion of safety investment of corresponding subsystems,the optimal investment scheme can be identified,and the actual contribution rate of each subsystem to the total level of laboratory safety risk management can be solved.Then focus is placed on the prevention and control of subsystem risk factors,a new path can be provided for colleges and universities to accurately identify the direction of laboratory safety investment and make management decisions.
