ABSTRACT:
Apparatus and method for production planning in a manufacturing facility is provided. The apparatus and method generates a plurality of theoretical plans and a constraint-based model for receiving one of the theoretical production plans, and applying at least one constraint thereto. Further, a cost function is computed for the theoretical production plans. Then, the apparatus and method searches for a feasible production plan among the plurality of theoretical plans, where the feasible plan is the plan which does not violate the applied constraint and has the least computed cost function.
