The physical operation is identified in the computer system as requiring use of a specific type of physical resource. The method includes determining whether at least one electronic resource object includes a physical characteristic attribute that meets a predefined requirement associated with performing the physical operation. The determination is made among at least one electronic resource object representing an individual physical resource having the specific type. A computer system includes a repository having stored therein the resource objects, and a resource management module configured to perform the determination.
