摘要
提出了在多种服务质量的非功能属性基础上,通过双向拍卖实现电子市场的服务交易.设计了一个多属性的双向拍卖模型并给出了相应的形式化定义.分别提出了基于服务质量属性和基于服务可信度的2个双向拍卖算法,并分析了2个算法均满足激励相容、预算均衡和个体理性的原则,符合电子服务交易的市场规律.仿真实验结果表明,2个算法均具有较好的稳定性,能够有效保障服务交易双方的收益并能提高交易的成功率;而基于服务可信度的双向拍卖,其平均交易成功率和平均总收益率均高于基于服务质量属性的双向拍卖.
On the basis of non-functional attributes of service qualities,double auction is proposed to deal with the transactions of Web services in the electronic market.A model of multi-attribute double auction is designed and the corresponding formalization definition is given.Two double auction algorithms are proposed based on service quality attributes and service credibility,respectively.It is theoretically concluded that two algorithms satisfy the properties of incentive compatibility,budget balance and individual rationality,which accords with the market law.Simulation experimental results show that these two algorithms have good stability and can effectively guarantee the profits of both sides,and improve the transactions＇ success rate;both the average success rates and the average total profits in the double auction based on service credibility are higher than those in the double auction based on service quality attributes.
