Abstract

In order to accurately identify main factors affecting emergency response for work safety accidents in small and micro enterprises, and improve response capabilities, firstly, a vulnerability evaluation system for safety accidents ' emergency response in such enterprises was established from a perspective of vulnerability. Secondly, Z-numbers was introduced to construct an vulnerability evaluation model which considered both subjective weight of AHP and objective weight of PCA. Then, fuzzy comprehensive evaluation method was improved by using Z-numbers, and vulnerability level was determined. Finally, model verification was conducted with a small and micro enterprise as an example. The results show that its emergency vulnerability index for safety accidents is 1. 756, rated as " relatively vulnerable". Among the four sub-systems, score of " environmental vulnerability" system is relatively low, which should be the priority for current prevention. © 2021 China Safety Science Journal.
