Techniques and systems for adjusting multiple hierarchies for consistency within levels of the hierarchies, using an optimization-based approach that results in an accurate projection across dimensions and levels in hierarchies. The systems and methods may include receiving data associated with nodes of two or more hierarchies, wherein nodes are associated with original node values, identifying a common level node and a target level node for each of the hierarchies, identifying a linking constraint, wherein the linking constraint includes a rule to a node from a hierarchy to make it consistent with a node from another hierarchy, applying the linking constraint to the common level node of each of the hierarchies, wherein applying the linking constraint includes generating updated common node values associated with the common level nodes, and wherein updated common node values are the same node values, applying the updated common node values to the target level node of each of the hierarchies, wherein applying the updated common node values includes generating updated target node values, and generating a resolved hierarchy using the updated target node values.

Systems and methods for resolving over multiple hierarchies

Computer-implemented systems and methods are provided for delivering products according to propagated changes in a demand planning hierarchy. Demand planning data is received in addition to a change to the product quantity or a disaggregation factor at a node of the hierarchy. The product quantity is updated at other nodes based upon the received change. Updating the product quantity at other nodes includes solving a set of simultaneous equations to generate an updated demand planning hierarchy. The simultaneous equations include a sum of the product quantity at a node and a augmenting flow at the node equals a sum of the product quantities of children nodes of the nodes and a relieving flow at the node, and disaggregation factors at the node and other nodes are implemented. Solving the set of simultaneous equations includes minimizing the sum of the augmenting flows of the node and other nodes.
