航运公司安全管理能力聚权分级模型

为了更好对航运公司安全管理工作摸底排查，采取针对性措施监管航运公司安全营运，需要对安全管理能力进行分类分级评价。基于表征航运公司安全管理能力的分级指标体系，建立安全管理能力分级评价模型。基于熵权和变异系数法的赋权方法，利用α系数检验两种客观赋权法的信度，提出聚合权重并建立安全管理能力的物元分级模型。利用多家航运公司数据确定分级指标的权重，对典型公司分级和评分。结果表明，提出的模型能合理反映各公司的安全管理能力，并有利于主管机关进行分类管理，采取针对性措施提高监管效率改善公司安全管理能力。

Model for ranking on safety management capability of shipping company based on aggregation weight

In order to sort out safety management work of shipping company thoroughly , and adopt specific measures to administrate safety operation of shipping company , the ranking evaluation of safety management capability should be carried out .Based on the characterization of ranking indexes system for safety management capability of shipping company , a ranking model was established .Based on entropy weight and coefficient of variation method , utilizing theα-coefficient , the reliability of the method was verified , the aggregation weights were proposed to determine the optimized values of weights , and a matter-element ranking model for safety management capability was structured .The ranking index weights from the data of shipping companies were used to rank typical companies . The results showed that the model demonstrated the level of safety management capability reasonably , and was advantageous to classified management for the administration , and implement corresponding measures to improve the efficiency of supervision and safety management capability of company .
