Abstract
Within both a system and a method for managing within a fabrication facility a work-in-process (WIP) workload within the fabrication facility there is first provided a fabrication facility comprising: (1) a plurality of fabrication tools which perform an equivalent fabrication function; and (2) at least one quantity of existing work-in-process (WIP) workload which requires multiple sequential processing within only one fabrication tool within the plurality of fabrication tools which perform the equivalent fabrication function. There is then determined for the plurality of fabrication tools a plurality of tool loading coefficients which take into consideration complete processing of the at least one quantity of work-in-process (WIP) workload which requires multiple sequential processing within the only one fabrication tool within the plurality of fabrication tools. There is then introduced into the fabrication facility a quantity of new work-in-process (WIP) workload which also requires multiple sequential processing within only one fabrication tool within the plurality of fabrication tools which performs the equivalent fabrication function, wherein the quantity of new work-in-process (WIP) workload is allocated to a fabrication tool within the plurality of fabrication tools having a most favorable tool loading coefficient within the plurality of tool loading coefficients.
