针对铁路大站段管理滞后的实际,从建立电话会议系统、建立信息分析处理机制、建立危急处理机制、规范调度管理等方面阐述了提升站段调度管理质量的措施。     

企业危机预测与识别模型

针对当前大部分企业危机预警模型只能报警,不能预测的现状,提出一种基于指数平滑法与模式识别的预警模型。该方法首先对企业运营的单项特征指标进行预测,然后对预测结果模式识别分类,同时判断企业的危机状态。最后,用实例验证该模型的有效性。

Protection efficacy of national wetland reserves in China

Wetlands have the most abundant biodiversity,the highest carbon sequestration capacity,and the highest values for ecological services per unit area,of all the world’s ecosystems.Practice has shown that establishing reserves is the most effective way of protecting typical ecosystems and their biodiversity,and saving rare or endangered wildlife.The Chinese government’s policy is to protect wetland systems by establishing reserves that encompass a massive network of wetlands,including wetland nature re-serves,internationally important wetlands,and wetland parks.Many are already established.The effect of protecting wetland nature reserves at the national level has not yet been reported.We used the latest database evaluating the protection value of wet-land reserves,and remotely sensed wetland maps(1978-2008) ,developed by the same mapping specialists and based on the same classification system,and related environmental data,to evaluate the effects of protecting China’s national wetland reserves over the last 30 years.We conclude that(i) the total area of wetland in the national wetland reserves has decreased over the last 30 years to 8152.47 km2,and just 8% of China’s net decrease in wetlands;(ii) about 79% of the 91 national wetland reserves are in a poor condition.These are generally located around the Yangtze River,Eastern Coast,the Three Rivers Source,and Southwest China.Protection measures should be undertaken urgently in these areas.Only 15% of national wetland reserves are under sound protection,and these are generally located in the upper reaches of the Songhua River;(iii) although 88% of national wetland re-serves are primitive(relatively natural) ,implying that the site selection has been scientific,a high percentage of national wetland reserves show early warning signs of decline and require urgent attention;(iv) based on our evaluation of protection effects and pressures on ecology,we have made a priority list of national wetland reserves,and propose several protection strategies.     

基于改进型AHP的食品质量安全时间序列预警模型的研究

运用改进型AHP建立食品安全状态的时间序列预警模型。模型采用3标度法构建判断矩阵可较为简单计算确定质量安全预警指标的权重,判断食品安全状态,应用食品质量安全技术标准和指标可建立食品安全状态预警模型,用于食品安全状态预警,并以稻米为例建立稻米质量安全预警模型,为建立其他食品安全状态预警模型研究提供参考,也可为食品质量安全监管部门进行食品监测与综合评价、科学监管提供参考。

企业财务危机与金融风险分析——企业财务危机的传导

企业部门的经济活动是金融活动的重要的微观基础,企业财务状态直接影响到金融的稳定。在非正常状态下,企业客观存在的资本结构、资产结构、负债结构及其相互关系,会引起企业的财务危机,企业的财务危机又会向金融机构传导,诱发金融风险。因此,采取必要措施应对企业财务危机,是防范金融风险的重要环节。
