Taguchi Capability Index (Cpm) Taguchicapability index is a statistical measure used to evaluate the performance of a manufacturing process in relation to its target value and specification limits. It is calculated using the formula: Cpm=USL−LSL6σ2+(μ−Target)2−−−−−−−−...
Process Capability Index shows how closely a process is able to produce the output to its overall specifications. It decides how consistent we are to our average performance.The calculation is done by separating the formula into two halves.
Statistics - Process Capability (Cp) & Process Performance (Pp) - Process capability can be defined as a measurable property of a process relative to its specification. It is expressed as a process capability index ${C_p}$. The process capability index i
S2) calculating the collision probability of the communication nodes which initiate the access requests in each frame through a total probability formula on the basis of the number of random access channels configured in each frame; S3) acquiring the average successful access probability of access nod...

Theoverall process performance indices, Pp and Ppk,most often uses the sample standard deviation, s, formula as an estimate for sigma. There are other methods available for estimating the overall (total) process sigma. The Cpk and Ppk will require two calculations and selecting the minimum value...
[8] introduced an assessment indicator for sustainability denoted as the “sustainability efficiency indicator” (SEI) defined by the ratio between a selected performance parameter (PP) and quality parameter (QP) for a specified RC; this has the mathematical formula as follows: (2)SEI=PPQP·RC ...
