基于灰色理论的主观信任计算方法

Calculational methods of subjective trust based on gray system theory

通过讨论传统信任模型和信任计算,提出了以灰色系统理论为基础的灰序白化评估算法.方法的基本原理是:以主体的网上交易额为参考序列,由客体对主体的关键属性评分构成计算序列,得出主体的信任水平序列,根据灰关联分析计算灰关联信任空间,求出序化点列,作序化点列图,得出白度序列,最后按照灰序白化分析得出主体的关键属性对主体的信任水平的影响次序.该算法克服了传统分析中将主体的关键属性对主体信任水平的影响大小视为相等的做法,具有评价可靠,可操作性强,适合软件自动处理等特点,在开放式环境中具有广阔的应用前景.

Through discussing the traditional trust model and trust calculation,gray-order-whiting evaluation arithmetic based on the Gray system theory was put forward.In gray-order-whiting evaluation arithmetic,network profit of company was regarded as numeric list of reference,the scores of company′ key attributes which were provided by customers were regarded as numeric list of counting,according to Gray sequence whiting analyze,key attributes correlative to company′ trust level was sorted by influencing degree.Th...
