基于生产过程工序能力的供应商绩效评价方法研究

Research on Performance Measurement of Supplier Based on Production Process Capability

针对我国供应商绩效的传统评价模型,在分析供应商绩效评价因素的基础上,把工序能力作为新的评价因素。首先根据质量检验等方法,选出那些有关键质量特性或对整体质量影响较大、容易出现不合格品的工序作为关键工序;然后以关键工序质量特性的CPK作为评价指标,运用层次分析法确定指标权重;最后计算零件工序总的CPK进行评级。

For suppliers traditional evaluation model of our country, and on the basis of analyzing factors of suppliers traditional evaluation, make process capability as a new evaluation factor. First, according to the quality of testing method, elect critical to quality characteristics or greater impact on the overall quality and prone to failed processes as key process. Then use the CPK of the key process’s quality characteristics as evaluation index, and use the AHP to determine index weight. At last , assess suppliers by the calculation of total parts CPK.
