12. A computer-readable medium, comprising executable instructions, the instructions configured to instruct a computing device to: obtain at least one Exclude ZDD rule component from a ZDD rule model representing a rule; identify covers within the Exclude ZDD rule component; remove identified covers to produce an abridged Exclude ZDD rule component by: expanding nodes in the Exclude ZDD rule component to include all attributes specified in the rule; identifying covers within the expanded nodes in the Exclude ZDD rule component; marking nodes associated with the identified covers in the Exclude ZDD rule component; and removing identified covers and marked nodes from the Exclude ZDD rule component to produce the abridged Exclude ZDD rule component; determine satisfiability of the ZDD rule model based on the abridged Exclude ZDD rule component; and provide graphical conflict information based on the satisfiability of the ZDD rule.

The computer-readable medium of claim 12 , further comprising executable instructions configured to instruct the computing device to: reorder nodes of the ZDD rule model so that marker node groups appear at a bottom of the ZDD rule model; remove nodes that point to a same node as the marker node; remove marker nodes that point to a one node; and reorder reordering nodes of the ZDD rule model back to an initial index.
