I'd ask why you need this complex of a data model, but I'm afraid of the answer.... With this many complex and overlapping conditions, you're almost certainly better off performing the desired transformation in a separate program (written in Java, Python, or something similar). You'd read the source records with a relatively simple query (or a small number of queries) and, walking through the results, calculate the outputs and add them to a small set of bulk insert or update statements. Once all the inputs are read and processed, you'd commit the insert/update statements and call it a day. Just my thoughts...
