“…Some researchers have implemented fuzzy theory into risk assessments of diverse fields, such as manufacturing corporations [16], construction project investment [17], traffic congestion [18], buildings [19], freight transportation systems [20], ship control systems [21], mines [22], and so on. The assessment data were expressed in their favor, such as fuzzy numbers [23]- [25], [30]- [32], intervals [33], [34], Z-numbers [35], triangular fuzzy numbers [16], [19]- [22], [26], [27], [36], trapezoidal fuzzy numbers [28], Pythagorean fuzzy numbers [37]- [40], linguistic term sets [17], [29], and double hierarchy hesitant fuzzy linguistic information [18]. In recent years, researchers have studied risk assessment from different technical models, different methods and different fuzzy evaluations.…”
