Study on Lot-Based Tracking Method of Production Logistics in Iron and Steel Industry

To solve the problem of production logistics control resulted from dynamic material batch in iron and steel industry, a lot-based tracking method is studied to realize the fine control of production logistics. It connects lots with processes by the process-lot-state vector, combined-lot-backward vector and combined -furnace-backward vector, establishing the tracking model of production logistics about process states. Its application of enterprises shows that the method can describe completely of material processing information in the whole practical production logistics. Then the ability of tracking orders is increased and accurate information is provided for decision. Finally it is satisfied to track the real-time state of production logistics and reduce the material delay.
