Taxonomy/supplement/Problem diagrams

Questions on problem diagrams and a problem frames: Do problem diagrams support more the architectural decomposition than the process based? Can we have a sequence of refinements also on the interface descriptions? What i mean by this question is: when looking at out batch plant modelling, i do not want to talk about valves in the first abstract representations. I want to talk about flow and operations of material, but not low-level technical solutions, even if these low-level solutions form the physical) interface between plant and control in the end. Does a control frame imply version 1 of the control decomposition?
