摘　　要：在目前的动态服务组合研究中,几乎没有涉及到服务组合的费用问题,也没有进行费用-效益分析.针对这些情况,首先提出了服务组合费用-效益分析决策框架,然后以旅游服务组合为对象,利用基于RICH的多层值树对其进行建模,并根据多层值树的特点,提出了一种权重极值的计算方法.信任值的多种不确定性,用区间值进行建模,并给出了信任值的产生和聚合方法.在进行费用-效益分析时,通过计算不同费用标准下的成本效率服务组合获得成本效率集合,在此基础上,依据用户偏好和决策准则作出决策.针对组合爆炸问题,提出一种优超算法.最后通过仿真验证该方法的有效性.In the research of dynamic service combination,the cost of service combinations is seldom taken into account and cost-efficiency analysis is not employed.The decision framework of service combinations for cost-efficiency analysis is presented.The multilayered value tree based on RICH is used to present tour service combination.Because of the characteristics of multilayered value tree,the weight extreme calculation method is presented.Interval value is used to describe various uncertainties of trust,and the generation method and aggregation method of trust value are selected.The methodology guides decision making by identifying what combinations of tour service are cost-efficiency with respect to the multiple evaluation criteria at different cost levels.In view of the problem of combination explosion,the dominate algorithm is proposed.The simulation results show the methodology is effective.
