Service composition is an effective method of combining existing atomic services into a value-added service based on cost and quality of service (QoS). To meet the diverse needs of users and to offer pricing services based on QoS, we propose a service composition auction mechanism based on user preferences, which is strategy-proof and can be beneficial in selecting services based on user preferences and dynamically determining the price of services. We have proven that the proposed auction mechanism achieves desirable properties including truthfulness and individual rationality. Furthermore, we propose an auction algorithm to implement the auction mechanism, and carry out extensive experiments based on real data. The results verify that the proposed auction mechanism not only achieves desirable properties, but also helps users find a satisfactory service composition scheme.

服务组合是一种基于成本和服务质量（QoS）将现有原子服务组合为增值服务的有效方法。为了满足用户的不同需求并提供基于QoS的定价服务，我们提出了一种基于用户偏好的服务组合拍卖机制，该机制具有策略性，可以有利于基于用户偏好选择服务并动态确定商品价格。服务。我们已经证明，提出的拍卖机制可实现理想的属性，包括真实性和个人理性。此外，我们提出了一种拍卖算法来实现拍卖机制，并基于真实数据进行广泛的实验。结果证明，提出的拍卖机制不仅实现了理想的性能，
