Systems and methods for supply chain management and identification of feasible plans. Identification of feasible plans includes collecting demands for one or more items having the same level code; and for each of the collected demands, determining a first demand shortage quantity, searching the data storage for available unallocated supply responsive to the first demand shortage quantity, determining a second demand shortage quantity, and creating supply, the creation of supply being responsive to the second demand shortage quantity and the creation of supply including satisfying a dependent demand at a higher level code. Satisfying a dependent demand at a higher level code may include using the system recursively. Using the system recursively may include incrementing a current level code. Satisfying a dependent demand at a higher level code may include performing a feasible plan search relating to items assigned the higher level code.
