Research on Quantitative Evaluation of Post Safety Competency of Port Operators

Abstract

This study took one subsidiary company of a certain domestic port group as a sample. Through job hazard source analysis, job demand analysis, open questionnaire survey, literature review, etc., the characteristics of post safety competency were collected and analyzed, and through statistical analysis of the sample data of the target positions, the reliability and validity analysis of the principal component analysis of the job competency characteristic elements were carried out to optimize and determine the theoretical model and its core characteristic elements, so as to establish the framework of the safety competency characteristic model of the target positions and form the post safety competency evaluation index system. Based on the objective weighting theory analysis method of system dynamics, the entropy weight of each level assessment index was calculated by using the information entropy of key post sample population, and then the weight of each level assessment index was corrected by the entropy value. According to the security requirements of mooring line workers, this paper carried out the theory of multilevel fuzzy comprehensive evaluation, the matrix model of multi-level safety fuzzy evaluation was established, and the fuzzy comprehensive evaluation was used for the third-level index, second-level index and first-level index successively, so that the comprehensive evaluation result of each level can be obtained respectively, and port operators’ post safety competency can also be quantitatively evaluated.
