Storage and management method for a multi-floor stocker system

摘要

A storage and management method for a multi-floor stocker system. The storage and management method combines a pull function and a push function with a from-to table to optimally distributed lots of work-in-process (WIP) to all stockers in the multi-floor system, thereby effectively utilizing every stocker. The from-to table is established by the following steps: evaluation of a step process time and a step equipment number; calculation of a step work ability for every stage based on the step process time and step equipment number of every product; and summary of the step work ability for every stage and production of a from-to table.
