Precedence ordering

In precedence ordering of realizational formulae, a second formula does not operate on some item after the first but instead of it. I.e., the second is allowed to operate only if the conditioning environment of the first does not apply.

Precedence ordering always involves formulae with the same symbol at the left of the arrow, and these rules are alternatives; i.e., they are in an either-or relationship to one another. The single symbol at the left corresponds to the single line above the downward ordered OR node in compact relational network notation. A single formula is used for each realizate, with a separate subformula (on a separate line) for each environment and realization. The subformulas are listed in the order of precedence, and since this is a precedence ordering of alternatives, they all occupy the same realizational level (stratum).
