HEURISTICS FOR EFFICIENT SUPPLY CHAIN PLANNING IN A HETEROGENEOUS PRODUCTION LINE

A computer integrated manufacturing system executes a program process that performs a capacity planning method that allocates usage of a plurality of manufacturing elements of a manufacturing enterprise by major and minor apparatus, squeezing for overhead cost consideration, and site balance for maintain basic operation. The program process begins by receiving at least one fabrication forecast describing scheduling and types of product lots that are predicted to be fabricated within a first period of time by the manufacturing enterprise from at least one order management system of the manufacturing enterprise. Rolling statistics of products lots fabricated during a second period of time are retrieved from a data retention device of the computer integrated manufacturing system. Capacity planning for the allocation of the product lot predicted to be fabricated by the manufacturing elements is performed.
