kapasitetsindekser
Kapasitetsindekser, often translated as capacity indices or capability indices, are a set of statistical tools used in quality control to assess the ability of a manufacturing process to produce output that meets specified requirements. These indices quantify how well a process's natural variation fits within the tolerance limits set for a particular product characteristic.
The most common capacity indices include Cp, Cpk, Pp, and Ppk. Cp (Process Capability) measures the potential
Cpk (Process Capability Index) is a more practical measure as it accounts for process centering. It is
Pp (Process Performance) and Ppk (Process Performance Index) are similar to Cp and Cpk, respectively, but they
Interpreting these indices involves comparing their values against established benchmarks. Generally, higher index values signify a
