Abstract: A demand driven pull-through computerized decision support scheduling system-- The Cube System-- employing a CUBEBOOKING Program operating in near real time to load Jobs (a sequence of predefined process) in CubeCells at a Workspace in Time defined in a selected Cube World in response to demand placed on the Cube World by a customer order, which program allocates the best available resources to produce products (Product Resources) composed of materials (Material Resources on a Positive Bill of Materials) having Features (contained in a Negative Bill of Materials). The Cube System operates to keep track of alternate probable process paths by scoring systems and retains resource usage production history patterns as Prime Data to resolve conflicts between capacity-limited resources (Resource Contentions).
