在面向服务的环境中,如何选择满足用户偏好的高质量服务是一个关键问题.以往的研究大多考虑单个用户选择服务的情形,多个用户协同选择一个共享服务的问题则较少得到关注.使用群决策支持技术,提出多个用户协同选择一个共享服务的方法.该方法首先根据用户偏好计算每个用户对候选共享服务的满意度,然后考虑不同用户的优先级计算多个用户对每个共享服务的总体满意度,最后对候选服务排序,并选择总体满意度最高的共享服务.我们方法的优点是不仅允许用户定义柔性的个性化属性偏好需求,而且可以平衡多个用户的不同偏好引起的冲突.
In the service-oriented environment, how to choose a high-quality service that meets the user’s preference is a key issue.Over the previous researches mostly consider the case of single user selecting a service, and the problem of multiple users collaborating to select a shared service seldom get attention. Group decision-making support technology, this paper proposes a method for multiple users to select a shared service collaboratively.This method firstly calculates the satisfaction degree of each user to the candidate shared service according to the user preference, and then considers the priorities of different users to calculate multiple users’ The overall satisfaction of the service, and finally the ranking of the candidate services and the selection of the most generally-satisfied shared services.The advantage of our approach is that it not only allows users to define flexible personalization preferences, but also balances the preferences of multiple users conflict.
