摘要 操船环境是指对船舶操纵产生限制的影响因素,操船环境危险度评价结果直接影响船舶的正常航行,而当前方法操船环境危险度评价模型存在评价结果主观性强,评价精度低等不足。为了提高操船环境危险度评价效果,设计基于关联分析的操船环境危险度评价模型,首先分析当前操船环境危险度评价研究现状,并构建操船环境危险度评价的指标,然后采用关联分析方法对原始操船环境危险度评价指标进行处理,确定操船环境危险度评价的权值,最后根据关联分析结果处理操船环境危险度评价数据,并构建操船环境危险度评价模型。与其他操船环境危险度评价模型进行仿真对比实验,结果表明,本文模型可以合理确定每一种操船环境危险度评价指标的重要程度,得到高精度的操船环境危险度评价结果,而且操船环境危险度评价速度更快,可以为船舶安全管理者提供参考。 Ship handling environment refers to the influencing factors that restrict ship handling.The assessment results of ship handling environmental risk directly affect the normal navigation of ships.However,the current assessment model of ship handling environmental risk has some shortcomings,such as strong subjectivity and low evaluation accuracy.In order to improve the assessment effect of ship handling environmental risk,a ship handling environmental risk assessment model based on correlation analysis is designed.The evaluation model firstly analyses the current research status of shiphandling environmental hazard assessment,and constructs the evaluation index of ship-handling environmental hazard.Then,the original evaluation index of ship-handling environmental hazard is processed by correlation analysis method,and the weights of ship-handling environmental hazard assessment are determined.Finally,the data of ship-handling environmental hazard assessment are processed according to the results of correlation analysis,and the ship-handling environment is constructed.The model of risk assessment is simulated and compared with other models.The results show that the model can reasonably determine the importance of each evaluation index of ship-handling environmental risk,and obtain the high-precision evaluation results of ship-handling environmental risk.Moreover,the assessment speed of ship-handling environmental risk is faster,which can provide valuable reference for ship safety management.
