【摘要】：针对云制造环境下因存在大量功能相同或相似的制造云服务而导致用户很难获得合适云服务的问题,提出了一种基于可信评价的制造云服务选择方法。对问题进行了抽象,将可靠性、可用性、时效性、价格和诚信度纳入可信特征集,并考虑评价时间、评价者的诚信度对可信值的影响,采用加权平均的方法计算制造云服务的整体可信度;在此基础上,综合考虑制造云服务的功能、任务负载、当前状态和物理距离等因素,通过匹配功能、任务负载和价格,并结合可信评价值来指导云服务的选择。仿真结果表明,所提方法能够有效地识别云制造环境下的制造云服务实体,可提高交易活动的成功率,满足用户的功能需求和非功能需求。
[Abstract]:In order to solve the problem that it is difficult for users to obtain suitable cloud services due to the existence of a large number of manufacturing cloud services with the same or similar functions in cloud manufacturing environment, a method of manufacturing cloud service selection based on trusted evaluation is proposed. The problem is abstracted, reliability, availability, timeliness, price and trustworthiness are incorporated into the trusted feature set, and the influence of the evaluator's trustworthiness on the trustworthiness is considered. The method of weighted average is used to calculate the overall reliability of manufacturing cloud service, on the basis of which, the function of manufacturing cloud service, the task load, the current state and the physical distance are considered synthetically, and the matching function, task load and price are taken into account. And combined with trusted evaluation values to guide the selection of cloud services. The simulation results show that the proposed method can effectively identify manufacturing cloud service entities in cloud manufacturing environment and can improve the success rate of transaction activities and meet the functional and non-functional needs of users.
