This system identifies bottleneck and makes the best use of bottleneck, then according to the production rhythm on ottleneck, pulls the working procedures before the working procedure on ottleneck and pushes the working procedures after it . This production planning system can produce a production plan w ith smooth material flow and less storage ,w hich increases the effective output really.
