Abstract

n the manufacturing process of any product intervene several factors associated with the monitored quality characteristics. These factors must be examined with adequate Statistical Quality Control tools to provide estimates of product specification compliance. For this purpose, Process Capability Indices are commonly applied to manufacturing processes, assuming that the quality variables are independent, and the data is normally distributed. Additionally, an increasingly prominent quality characteristic across manufacturing industries is product reliability. This paper explores the advantages of using multivariate capability indices that include product reliability as a key quality criterion.

摘要

n 任何产品的制造过程都会影响与监控的质量特性相关的几个因素。必须使用适当的统计质量控制工具检查这些因素，以提供对产品规格合规性的估计。为此，过程能力指数通常应用于制造过程，假设质量变量是独立的，并且数据是正态分布的。此外，制造业中一个日益突出的质量特征是产品可靠性。本文探讨了使用将产品可靠性作为关键质量标准的多元能力指数的优势。
