求翻译:Interpretation Process capability index, Cp, reveals that process is currently producting wafers that do not meet the specifications. The Cpk value is equal to the Cp value; that is, the process is close to being centered within the specifications。是什么意思? 待解决 悬赏分:1 - 离问题...
In the case of individual values, the estimate of standard deviation for capability indexes comes from “average moving range” ÷ 1.128. Sarah finished by saying that capability indexes are predictive indicators, and the confidence in the prediction is dependent on the interpretation ...

Interpretation of process capability index and the meaning of Cpk statistics Now that you're familiar with the process capability index formula, how to calculate the process capability index, and what Cpk is, let's talk about its interpretation. As mentioned before, the higher your Cpk value, ...
It is considered that the existence of neutral answers is due to the interpretation that the institution had about the capability levels that were assigned when the self-evaluation was answered. This indicates that capability levels need to be explained more clearly, because despite the fact that ...
4. Considering the organization’s capability and resources, a policy must be realistic to ensure its implementation. 5. A good policy should uphold internal consistency by aligning with other policies, not contradicting them. 6. An effective policy i...
Thep-value for either the predictability ratio or the stability ratio may be used as a one-number summary to characterize the predictability of a process during a baseline period. These ratios may be computed from capability and performance ratios, or they may be computed directly using th...
MaintainabilityTestabilityCapability to enable validating the evolving component-based system Some researchers used metrics which have been collected per source file (Khoshgoftaar, Gao, & Szabo, 2001; Ostrand, Weyuker, & Bell, 2005) and we call these metrics “file-level metrics”. Some of these...
