摘要
文章针对区域内重点企业风险监测评估问题,提出了一种基于相关时间序列的企业动态风险指数的监测评估模型,建立了企业风险监测评估指标体系。通过分类数据实时采集,利用Z-score对各类企业风险数据进行归化处理,生成基于时间序列的风险强度矩阵,并叠加相关时间序列的风险衰减函数,利用熵权法给风险指标赋权,最后计算风险指数,对区域重点企业风险进行监测评估。仿真结果表明该方法是一种解决区域企业风险监测评估的有效方法。
Aiming at the problem of risk monitoring and evaluation of key enterprises in the region,this paper puts forward a monitoring and evaluation model of enterprise dynamic risk index based on correlation time series,and establishes the index system of enterprise risk monitoring and evaluation.Through real-time collection of classified data,all kinds of enterprise risk data are naturalized by Z-score.The risk intensity matrix based on time series is generated,and the risk attenuation function of related time series is superimposed.Entropy weight method is used to empower the risk index,and finally the risk index is calculated to monitor and evaluate the risk of regional key enterprises.The simulation results show that this method is an effective method to solve the risk monitoring assessment of regional enterprises.
