Kappa analysis of industrial park risk evaluation index system

摘要：

　　In the industrial park regional risk evaluation process,expert evaluation method is usually used to budget the constructed index system,so that the overall park risk value can be quantified.During setting the estimation system and expert assignment,in order to comply with the objective factor,Kappa statistics analysis method is adopted to evaluate the consistency analysis of the system setting of regional risk estimation and the experts assignment situation.The Kappa statistic is an statistical index which via comparing two or more observers on the same things,or the twice or more observation results of one observer on the same thing,and the difference between the consistency and the consistency of actual observed value,which is caused by opportunity or by actual measurement,is used as statistical index.Kappa statistic and weighted Kappa statistic not only can be used to inspect the consistency and the reproducibility of ordered and unordered variable data,but also can give a magnitude which reflects the consistency.During the course of assessment,experts coming from different departments give respective grades of safety conditions in industrial park.Then indexes setup and grades by experts are discussed.The results indicate that grades by experts show good consistency.
