摘　　要：为了更好地从大量候选云服务集中选出满足制造需求且服务质量较优的制造云服务协同完成制造任务,针对QoS准确性给组合筛选带来的影响,基于接口关联、业务实体关联、统计关联,提出了一种支持服务关联的QoS感知评估模型。引入企业合作时间、KULC和IR参数,利用历史信息进行预测对统计关联QoS变化量进行动态调整,保证了时效性。通过算例分析验证了所提方法的可行性,实验结果表明该方法能为服务需求方提供更切合实际的解决方案。In order to select better quality of manufacturing cloud services that meet the demand of manufacture to complete manufacturing tasks in coordination,a QoS aware evaluation model supporting service correlation was proposed based on interface correlation,business entity correlation,and statistics correlation,aiming at the impact of QoS accuracy on combination screening.The cooperation time,KULC and IR parameters were introduced,and the historical information was used to predict and dynamically adjust the statistical association QoS changes to ensure timeliness.The feasibility of the proposed method is verified by an example analysis,and the experimental results show that the method can provide a more realistic solution for the service demander.
