摘要
通过分析与溢油污染程度有关的影响因素,构建海上石油平台溢油污染程度评价指标体系。结合粗糙集属性重要度理论,将权重确定问题转化为粗糙集中属性重要性评价问题,建立海上石油平台溢油风险的关系数据模型,计算出风险评价模型的权重。该方法克服了传统权重确定方法的主观性,使风险评价方法更具客观性,为计算溢油污染指标权重提供新方法。
Establishes assessment index system of oil spill for the offshore oil plat form by analyzing the influenced factors related to the degree of oil pollution. Combining with attribute rough set significance, translates determining weight into estimating significance of attributes among rough sets. Establishes a relation data model about Oil Spill on Offshore Platform risk assessment, calculates the risk assessment model weights. The proposed approach overcomes the subjectivity of traditional determination to weight, and makes risk assessment more objective, the model could provide new method for oil pollution index weight calculation.
