摘　　要：在分析对制造质量控制信息要求的基础上,研究了与质量功能展开(QFD)集成的制造质量信息,提出了用工序的困难程度Rdif、重要程度Rimp和熟练程度Rpro3个指标表示制造质量控制水平与能力的方法,给出了Rdif、Rimp和Rpro的计算模型。It is still quite rare in China to feedback manufacturing quality information to interact with QFD （Quality Function Deployment）; QFD is the quality control tool used in product design. In a previous paper, we propose using three parameters degree of difficulty Rdif, degree of importance Rimp, and degree of proficiency Rpro--as manufacturing quality information to be feedbacked for integration with QFD. In this paper, we provide methods for calculating Rdif, Rimp, and Rpro. Rdif is calculated by the following four parameters： process capability Cp, ratio of process quality problems Qa, ratio of abnormal control charts or processes Ca, and the index indicating a process returning abnormal state to normal state. Rimp is calculated by the ratio of the quality problem number to the total problem number. Rpro is calculated according to how frequently a process or processes which are close to a new process have been done in the history of manufacturing; dynamic evaluation principle is used in the calculation of Rpro ; two methods for calculating Rpro are given. Our method of calculation was applied by a design team to providing the abovementioned three parameters for integration into QFD design of a certain hydraulic servo actuator; the design team found our method of calculation to be effective.
