Abstract
A system and method is disclosed for solving supply chain planning problems. The system includes a database that stores data representing a planning problem of a supply chain network and a computer configured to access the planning problem of the supply chain network stored in the database and model the planning problem as a network of nodes and edges. The computer is further configured to generate a hierarchical linear programming solution of the planning problem and apply advanced heuristics to the generated hierarchical linear programming solution. The computer is still further configured to formulate a mixed integer program to generate an optimized global hierarchical solution and store the generated optimized global hierarchical solution in the database.
