| 摘 要： | 应用信息扩散原理,通过扩散函数对不完备信息进行适当的信息膨胀,建立观测样本和风险概率分布的映射关系,构建了基于信息扩散的城市区域安全生产风险计算模型.并以某市新北区的安全生产风险作为研究对象,选取该区域2005-2010年各年度建筑施工事故、火灾事故、工矿商贸事故的死亡人数和地区亿元GDP死亡率作为该区域安全生产风险的...

| Abstract: | The small sample with incomplete information was employed to assess the urban regional work safety risk.Based on the methodology of information diffusion which could fuzzify single sample point,the mapping relationship between observation sample and risk probability distribution was studied by properly expanding the incomplete information with the diffusion function applied the principles of information diffusion,and a work safety risk calculation model of urban region based on the information diffusion was... |
