System and method for rule location, ordering, and combining in a polyhierarchical environment are described. In one embodiment, a polyhierarchical environment contains at least one rule, at least one logical structure representable by a graph and at least two connections between one or more of the logical structures and a rule set evaluator (RSE). The RSE retrieves an assembly definition associated with a particular ordering or combination of rules. Each assembly definition is associated with one or more location chains, and each location chain is associated with one of the connections to a logical structure. For each location chain, a rule location policy is invoked, returning a rule. An assembly policy is invoked upon the returned rules, forming the returned rule into a dataset that conforms to the ordering or combination associated with the assembly definition.
