Abstract: A particular assembly is exploded into a first structure specifying multiple levels each comprising at least one component configured within each of the levels. One or more differences are detected from any level of the first structure of the particular assembly for the demand and to any level of a second structure of one or more selected completed assemblies from among the one or more completed assemblies. An order is allocated to the demand, based on the one or more differences, of at least one of a set, a subset, and a superset of the one or more selected completed assemblies, for efficiently managing manufacturing of configurable products within the configure-to-order environment.
