Abstract

A system and method for driving new technology WIP at a controlled speed side-by-side with production WIP using a common range management infrastructure. The system and method allow new technology WIP and production WIP to be driven together in the same fabricator with the same degree of speed and predictability. The system and method may include at least one device configured to create a target based on a sum of active WIP targets for at least one route, find all lots of active WIP on the at least one route, tag each of the lots until a first occurrence of a sum of WIP of the tagged lots exceeds or equals the target, and assign a priority to each of the tagged lots based on a predetermined criteria.
