摘要
针对影响船舶LCC的因素很多,且各因素之间又相互影响,要根据这些因素建立船舶LCC的估算模型比较困难,提出了综合分析的方法;该方法使用了粗糙集进行聚类分析,对各因素进行初步约简,然后使用关联度进行相关性分析,对各因素进行进一步的约简,最后使用主成分进行主元分析,得到约简后的因素;运用上述方法减少影响船舶LCC因素的维数,降低建立船舶LCC估算模型难度。
It＇s difficult to build a rough estimate modal based on its influence factors for the large amount factor numbers,as well as those factors all have influence to each other.Therefore,the integrative analysis method is provided.Clustering Analysis is used through rough set to make preliminary reduction for those factors. Then takes relevance into relative analysis for further reduction.Final reduced factors are achieved after principal component analysis.By utilizing former method,the influencing factors on ship LCC are decreased meanwhile ship LCC rough estimate modal can be more conveniently set up.
