Abstract: To solve the service selection problem in cloud manufacturing environment,a selection model based on capacity resource demand orders was put forward from capacity resource.Assessment system for capacity resource demand was established,and the efficiency value of capacity resource demand orders was obtained by combining with supply preference of capacity resource provider and using variable precision rough set theory.It provided important reference for capacity resource provider to choose capacity resource demander.The experiment results showed that the model could accurately select the most suitable capacity resource demander for capacity resource provider.

Key words: cloud manufacturing, capability resource demand, efficiency value, supply preference

摘要： 为了解决云制造环境下的服务选择问题,从能力资源的角度提出了一种基于能力资源需求订单效率值的选择模型。通过建立能力资源需求的评价体系,引入变精度粗糙集理论计算各评价指标的权重,结合能力资源提供方的供给偏好,求得多个候选能力资源需求订单的对应效率值,为能力资源提供方选择能力资源需求方提供重要参考依据。通过实例证明了该模型能够准确地为能力资源提供方选择最佳的能力资源需求方。
