本文将过程能力指数作为衡量供电企业运营能力的指标,结合供电企业运营现状和自身特点确定了关键运营过程,在此基础上构建了评价指标体系,研究了基于过程能力指数的评价方法。最后通过实证表明,利用过程能力指数对供电企业运营能力评价,并结合控制图对其过程进行监督管理,可以有效地反映供电企业运营能力的变化情况以及存在的不足。 In this paper, the process capability index is used as an index to measure the operation capability of power supply enterprises. The key operation process is determined by combining the current operation status of power supply enterprises and its own characteristics. Based on this, the evaluation index system is constructed and the evaluation method based on process capability index is studied. Finally, it is proved empirically that using the process capability index to evaluate the operation capability of the power supply enterprises and supervising and managing the process combined with the control chart can effectively reflect the changes of the operation ability of the power supply enterprises and the existing shortcomings.
