由于每种过程能力指数都不完美且可能产生误导,因此,没有一种指数可以广泛地应用到所有过程中;同时,由于过程的多样性以及过程质量的多维性,没有一个过程可以由一种指数完全描述。本着简洁性、全面性、可比性及实践指导性原则,文章构建了过程能力指数体系,定义(或解释)了每个指数的含义,介绍了指数体系的使用方法,旨在通过指数间的互补性,全面、客观地衡量各类过程的质量。 Because each process capability index is imperfect and may be misleading, there is no single index that can be applied broadly to all processes. At the same time, due to the diversity of processes and the multidimensional nature of process quality, none of the processes can be represented by a The index is fully described. In the principle of conciseness, comprehensiveness, comparability and practical guidance, the article constructs the process capability index system, defines (or explains) the meaning of each index, introduces the use of the index system, Complementarity, comprehensive and objective to measure the quality of various types of processes.
