Demand breakout for a supply chain

Software for demand breakout for a supply chain, the software embodied in at least one computer-readable medium and, when executed using one or more computer systems, operable to:

• access a plurality of orders for at least one product, each product produced using at least one precursor;
• access a production schedule identifying one or more resources in the supply chain, a quantity of each product and precursor scheduled to be produced by the one or more resources, and a time period associated with production of each product and precursor;
• generate a first event for each product order, the first event comprising a request for a specified quantity of a specified item, the first events forming a first layer in a tree;
• generate a weighted average for each of the first events, each first event associated with a plurality of attributes and an attribute value corresponding to each attribute, at least one attribute value being representative of customer importance, each attribute associated with an attribute weight, the weighted average based on the attribute values and the attribute weights;
• execute the first events in order of decreasing weighted average by:
• determining a specified quantity of one or more specified precursors needed to produce the specified quantity of the item requested by the first event;
• determining if at least one of the precursors needed to produce the item requested by the first event is too scarce to produce the specified quantity of the item;
• determining a fractional quantity of each specified precursor if at least one of the precursors is too scarce;
• and
• generating at least one second event for each of the specified precursors, the second event comprising a reservation of one of the specified quantity of the specified precursor or the fractional quantity of the specified precursor;
• execute the second events to produce one or more additional first events in a second layer of the tree;
• and
• propagate the first and second events through any additional layers of the tree to allocate one or more particular units of one or more precursors to each product order.
