摘要:针对当前石油公司在液货船安全检查和准入审查中存在的非定量、非智能评估问题,引入人工智能技术构建液货船综合安全评估(formal safety assessment, FSA)专家系统模型。该模型将FSA方法与专家系统进行组合,前者通过风险识别、风险衡准和风险量化,解决报告的非定量评估和审查的主观性问题;后者引入K最近邻算法、加权赋值算法等解决审查评估的非智能化和效率低的问题。选取官方案例进行模型检验,其结果表明提出的模型能有效地帮助石油公司实现船舶准入审查的定量化、智能化,并能显著提高审查效率,降低人工评估的主观性影响。

Abstract:
Aiming at the non-quantitative and non-intelligent assessment problems in the safety inspection and access review of tankers in oil companies, the artificial intelligence technology is introduced to construct the expert system model for formal safety assessment (FSA) of tankers. In the model, the FSA method is combined with the expert system. The FSA method is used to solve the problem of non-quantitative assessment and subjective review of reports through risk identification, risk balance and risk quantification; the K-nearest neighbor algorithm and the weighted assignment algorithm are introduced to the expert system to solve the problem of non-intelligence and low efficiency of review evaluation. Official cases are selected to test the model. The test results show that, the proposed model can effectively help oil companies to achieve the quantification and intelligence of ship access review, and can significantly improve the efficiency of review and reduce the subjective impact of artificial assessment.

航運是一个高风险行业,而液货船由于其所运输货物本身的高危性,海上航行风险更大。一旦液货船发生事故,人命安全、财产、海洋环境将会遭受十分严重的损害。目前,船舶安全检查主要以国际海事组织(International Maritime Organization,IMO)和国际劳工组织(International Labor Organization,ILO)颁布的有关法令法规为依据开展工作,而各行业组织的行业检查同样以上述方式展开。针对液货船和液货船所属船公司,目前……
