ABSTRACT:
Embodiments of the invention provide a computer-aided production planning method and system for accurately and quickly drafting a production plan for a given period for a production system employing a production line with a salvage process. In one embodiment, the method includes a new parts supply quantity recalculating step of recalculating the quantities Xi,jof parts to be newly supplied based on obtained actual product yields Bj, actual production process total supply quantity ratios Ci,j, actual production process salvage ratios Di,j, the requested quantities Ajof finished products, and correction parameters Fi,jfor the actual production process total supply quantity ratios Ci,j; and a production process load determining step of, to draft a production plan for a given period, determining the load on each production process of the production line on each day based on the quantities Xi,jof parts to be newly supplied in such a way that the requested quantities Ajof finished products can be produced, the quantities Xi,jbeing recalculated at the new parts supply quantity recalculating step.
