Abstract: Exhibition logistics exhibits had transportation risks, and the traditional risk assessment methods were difficult to complete the task efficiently. A risk assessment method based on fuzzy fault tree was proposed based on the case of the 3rd China Garden and Garden Horticulture Exhibition in 2020. The exhibition logistics exhibits transportion failure fault tree was established, the consistent decision was used to synthesize expert opinions, the de-fuzzy output was used to get the probability of the bottom event, and the weak links of the top event were obtained by comparing the importance of fuzzy probability. The results showed that the weak links that affecting the transportion failure of exhibition logistics exhibits were mainly the complex road conditions of transportation lines, fatigue driving of transportion vehicle drivers and poor safety awareness of transportation vehicle drivers.

Key words: fuzzy fault tree, exhibition logistics exhibits, transportation risk assessment
