Factors analysis and safety risk assessment of port dangerous cargo container yard location

Due to the inflammable, explosive and toxic characteristics of the goods stored in the container yard of dangerous goods, its operation risk once out of control is likely to lead to serious production safety accidents, causing huge losses to personnel, property and society, and emergency handling of accidents is also very difficult. This paper systematically analyzes the index elements in the site selection process of dangerous cargo container yard, and establishes a multi-level and multi-dimensional risk assessment index system. Ahp is adopted to assign the weights of the evaluation index system, fuzzy comprehensive evaluation rules are finally proposed, fuzzy mapping relationship is established, fuzzy matrix and weight vector are used to calculate the evaluation vector to achieve the quantitative evaluation conclusion, and a risk assessment method combining AHP and fuzzy comprehensive evaluation is formed for the port dangerous cargo container yard. The effectiveness of the technique is verified by an example of the site selection of a port loading and storage yard for dangerous goods.
