• The Architecture parameter, which identifies the architecture to be analyzed

• The Physical Resource Subset parameter, which is optional. This parameter is used to reduce the scope of the study to a subset of the physical resources defined in the architecture. If this parameter is not set, all the physical resources defined in the architecture are taken into account.

• The Service Subset parameter, which is also optional, indicates the services to be analyzed. If this parameter is not set, all the services defined in the architecture are taken into account.
