Application of Delphi Method in Screening Hygienical Evaluation Indices for Metro Operation Environment
摘要
Abstract
[ Objective ] To establish a hygienical evaluation system suitable for metro operation environment. [ Methods ] An alternative evaluation indices system was established based on literature review, then the indices were screened using Delphi method. [ Results ] Two rounds of experts consultations showed the responding rates of experts were 90％ and 100％ respectively and the mean of expert authoritative coefficients was 0.73. Lasdy, 12 detectable indices( four indices for each of physical, chemical and biological indicator groups ) were selected to combined final evaluation indices system. All variance coefficients of these 12 indices were less than 0.3. Additionally, the final coordination coefficient was 0.942 and the P value of the Chi-square test was less than 0.10, X2=32.03. [ Conclusion ] Experts involved all paid more attention to this study. The desirable responding rates,authoritative coefficients and coordination coefficients demonstrated that the indices system is reliable and may truly reflect the condition of metro operation air quality.关键词
