“…To solve these problems, a data-driven risk assessment model, based on Dempster-Shafer evidence theory (DST) [20,21], Deng entropy [22] and risk matrix [23], is proposed. Due to effectively deal with uncertain information, DST is widely used in decisionmaking [24][25][26], risk analysis [27], information fusion [28,29], uncertainty measurements [30], fault diagnosis [31][32][33], time-series [34], IoT applications [35] and many other fields [36,37]. Since most experts prefer to express their opinions with linguistic information, such as good, better, best, bad, worse, worst, DST can effectively deal with uncertain information about linguistic expressions involved in risk evaluation [38,39].…”
