Batch-based description method of material process state for iron & steel industry

To satisfy requirements on Work in Process(WIP) material management in iron and steel industry,a batch-based description method of material process state for iron steel industry was put forward after analyzing the description demands of material process state.Associating batches with processes,data of process dimension was presented by process batch state vector,combinatorial batch backward vector and combinatorial furnace backward vector.Transition rules were formulated.A novel 3D description model of material process state was constructed by combining attribute and time dimensions.Application example revealed that this method could cater to complete description of material process state and WIP material management for iron steel industry.
