为使结果更具适应性和普遍性,运用粗糙集数据处理系统对由6个因素组成的海船船员适任决策表进行数据约简.结果表明:较低航海教育程度者对海事发生的隶属度较高;船长对海事发生的隶属度最高;具有12个月以上本职务服务资历的海船船员,其服务资历与发生海事的隶属度成反比.对一般及以下等级海事事故,值班时间在0004~0008的海船船员对海事事故发生的隶属度较高;34~39年龄段的海船船员具有较高的隶属度.对大事故及以上等级海事事故,值班时间在0000~0004的海船船员对海事事故的隶属度较高;海船船员年龄与海事发生的隶属度成反比.
In order to make the result more adaptable and universal, the data reduction of data of the six-member seafarers’ competency decision-making table using the rough set data processing system is carried out. The results show that the lower sailing education degree belongs to the maritime affiliation The highest degree of mastership maritime affiliation; seafarers with seafarers with 12-month service qualifications over the service experience is inversely proportional to the maritime affiliation occurs.
