OPS.11:4.2 - Identify the structures needed for this question
For each selected structure, recover the actual constituents, obtaining relations, applied constraints and use. Say what the current view shows and which material features it omits.
Use A.22 for the general structural question. Use E.18 for one transformation-flow structure and E.18.2 for a mathematical description when that lens is useful. Select an E.18.NET network only when at least two transformation-flow structures are independently identified and obtaining cross-flow relations connect their positions under the applicable constraints and use frame.
A branching process, several views of one flow, and several independently identified flows are different cases. Financial or decision relations need not be reclassified as a transformation flow to be relevant. If a required relation or identity cannot be recovered, retain the proposed description and name the missing basis.
