Abstract: Aiming at the diversity and dynamics of manufacturing process information,polychromatic sets were used to represent elements characteristics and their constraint relationships.Based on representation of process information for process model,the process information was organized was established with process characteristics by taking the process activity as unit.Constraint relationships among process information were defined,process information was able to be expressed thoroughly with complicated features.The reasoning matrix of process dynamic scenario was established and calculated.The deductive method to express the multi-view of attribute information in manufacturing process stream model was proposed to provide multi-view perspective for attribute information in process stream model.The proposed method was flexible to the mapping and extraction of complete manufacturing process information at different level and constraints,and was better serving for different system integration and process information utilization requirements.

Key words: manufacturing process information model, dynamic setting, process stream model, polychromatic sets
