Abstract
A self-adjusting prediction system that provides for the transmission and storage of push lots of work. It uses an adaptive control algorithm in it's methodology to improve Automated Material Handling Systems (AMHS) transmissions. The method of prediction is greatly enchanted to reduce overall cycle time, incorrect transmission of work lots, and idle manufacturing tools. It provides real-time updating that enables a complex manufacturing Fab to process work with optimum movement between tools.
