Abstract
In one aspect, the invention relates to a method to propagate relations between a first rule set and a second rule set wherein the first and second rule sets are invoked by a common workflow model. The method includes tracing paths forward through the workflow model from the first rule set to the second rule set. Enumerating relations that extend forward from the first rule set to the second rule set is another step in the method. Additionally, using multi-valued logic, calculating the effects on the relations of control flow through the workflow model from the first rule set to the second rule set, tracing paths backward through the workflow model from the second rule set to the first rule set, enumerating relations that extend backward from the second rule set to the first rule set, and using multi-valued logic, calculating the effects on the relations of control flow backwards through the workflow model from the second rule set to the first rule set are also steps in the method.
