Construction and Application of SPA Based Safety Management System Assessment Model

摘要

The safety management system assessment (SMSA) model was built up on the basis of set-pair analysis (SPA) theory and its effectiveness was verified by practical application research. The assessment model of five-element identical-discrepant-antithetical connection number vector was formed in that the indicators were divided into five grades. The calculation of connection number component was simplified as rigorous rules were made for the grades division of indicators. The judging rule of grading safety management system (SMS) was established under the principal of confidence level. The applied research was conducted, which demonstrated that the SPA based assessment model could provide credible conclusion because the results highly agreed with those of BNWSS audition. In addition, this model can be applied to assess SMS of all levels and makes scientific judgment for future state of SMS.
