Models can have one of the following states or specific combinations of those:
The following combinations are possible:
Models that the engine will use for starting new processes are in Active state. This state is determined by checking the validity (valid from / valid to), the disabled flag and/or priority setting.
All models that are either in Active state or which have running processes, have the state Alive.
If model processes are marked as disabled (suspended), the model has the state disabled. Note that a model marked as disabled might still be Alive.
Models that are not Alive, which means they are not active and have no running processes, are in Inactive state.
