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
