在服务选择中，最终用户通常将他或她的个人偏好强加于候选服务的非功能属性。对于由一组用户推动的服务选择过程，候选服务通常由可能具有不同偏好或优先级的一组最终用户评估。在这种情况下，在用户的各种偏好或优先级之间进行权衡通常是具有挑战性的努力。针对这一问题，提出了一种多准则决策方法--层次分析法，将定性的个人偏好和用户优先级转化为数值权重。在此基础上，提出了一种基于层次分析法的QoS服务评价方法。最后，通过一个实例验证了该方法的可行性.
In service selection, an end user often has his or her personal preferences imposing on a candidate service's non-functional properties. For a service selection process promoted by a group of users, candidate services are often evaluated by a group of end users who may have different preferences or priorities. In this situation, it is often a challenging effort to make a tradeoff among various preferences or priorities of the users. In view of this challenge, a multi-criteria decision-making method, named AHP (Analytic Hierarchy Process), is introduced to transform both qualitative personal preferences and users' priorities into numeric weights. Furthermore, a QoS-aware service evaluation method is presented for a shared service's co-selection taking advantage of AHP theory. At last, a case study is presented to demonstrate the feasibility of the method.
