Abstract: To analyze and optimize manufacturing operation process quickly and accurately，a process hierarchy analysis method based on the status mode is proposed.The status model described the performances of processes and their influencing factors with internal mechanism.Using process knowledge of the status model expressed in the form of ontology，process performance influence relation graph is generated to express performance influence relation among elements of activities in a process.Performance influence relation graph is transformed into hierarchical structure.Applying the method of analytic hierarchy process，key status attributes that had great impact weight are found out.With the impact-weight status-gap matrix of status attribute，key points are found out that had great impact on process performance.Automatic generation of hierarchical structure from status model is simpler，more objective and more accurate than artificial generation.Feasibility and practicability of the proposed method are verified by an instance.
