摘　　要：基于石化企业综合自动化的需求,提出了多分辨率层次化物流模型建模框架和形式化描述方法,对物流模型的空间映射和时间推演作了统一数学描述,给出了多分辨率物流模型一致化检验的判据。然后以生产执行系统MES物流模型为例,具体介绍了石化多分辨率物流模型的建模方法、时空推演算法和模型验证策略,实际应用表明了多分辨率物流建模方法的有效性。An approach for hierarchical material flow modeling and its formalization description based on multi-resolution modeling （MRM） were introduced to meet the demand of integrated automation for the petrochemical industry. The strategy of model spatial and temporal mapping and the definition of model consistency were also proposed. The process of multi-resolution material flow modeling and the strategy of model mapping and validation in the petrochemical industry were presented in detail by the example of manufacturing execution system （MES）. Practical applications indicated that the hierarchical material flow modeling method was quite effective.
