【 摘 要 】

In order to reduce the accident rate of laterite nickel ore ships under severe weather conditions, this paper adopts the method of establishing fuzzy comprehensive evaluation mathematical model, which mainly considers the moisture content of the laterite nickel ore carried by the ship, the influence of wind and waves and the ship's own situation. The main factors and set the corresponding evaluation set, through the analysis of the importance of the corresponding factors, thus constructing a fuzzy set of choice levels, and then based on the principle of maximum membership, to comprehensively judge the dangerous level of the ship.
