In order to explore the flexible organizational pattern of operational resources under information conditions, role concepts are introduced for standardizing the management of the operational resources information. This paper builds up a Layered granularity structure model of operational resources organization, analyzes the self-related structure and attributes within the operational resources and proposes the process of operational role encolding suited to the operational substance cell data based on the above mentioned. The case application is validates that the approach proposed in the paper can confirm the flexible unification between expression and information standardization for physical entities, and it is easy to realize dynamical extending and compatible criterion within different layers, which provides a basic support in designing and modeling flexible organization for operational resources.
