Research Of Prestige Reporting Mechanism Based On Gray System Theory

Along with the constant development of the Internet, people are increasingly adapt to the concept of advances in information technology. Online transactions develop rapidly in this background.However,as the two sides in online transaction communicate with each other indirectly,trading of mutual trust is an important basis and prerequisite for the succes s of the transaction,which is closely related to the development of e-commerce. Trust asse ssment has become a hot research by scholars at home and abroad.Traditional Trust evaluation is based on probability and statistics. Traditional trust evaluation system includes recommendation database and collaboration-filter system.Recommendation information in recommend database is subjective and trust evaluation is vulnerable to malicious recommendation.Collaboration-filter system assumes the rating power of each customer equal.so it can't reflect the actual trust value of the entity.Through researching the related theory and key technology of trust assessment in the network environment against key issues,such as malicious recommendation and user rating power, firstly prestige reporting mechanism based on gray system theory using gray clustering evaluation arithmetic is designed. The necessary and sufficient conditions for the entity'gray relation degree is proved. It is proved that in the t time the existence of the entity'gray relation degree is sufficient and necessary. In this scheme original data is collected through using taste concourse method, Using gray relation analytical method, the evaluated vectors of the entities can be gotten.Through Inducing and adjusting according to the arranged gray level,trust degree of the entity can be obtained.The mechanism can effectively avoid malicious recommendation and avoid disadvantage of traditional assessment,in which the rating power of every customer is regarded as the same.Secondly,gray-order-whiting evaluation arithmetic based on gray system theory is put forward.which quantifies the influence of the key attributes to the trust level of an entity to sort key attributes.This arithmetic gives improved scheme for trust level of an entity.Finally, a simulation system is designed and implementated.The putting forward of prestige reporting mechanism based on gray system theory and realization of the simulation system shows trust can be quantified and trust among entities can be compared.The scheme has some advantages, such as credible evaluation,strong maneuverability,suiting the automatic processing of software etc. It has broad application prospect in open environment.
