Youíll learn how to select the right attribute data control chart, and how to create those control charts. These include the NP Chart, the P Chart, the U Chart and the C Chart. To do this you must ...

In this paper we derive the operating characteristic of the control chart for sample means when process standards are unspecified. Under the null hypothesis the distribution of the process is N(μ, σ2) ...

Control charts that are properly constructed and maintained prevent false out-of-control signals and provide a useful method for monitoring a process. Process control is and has been an important ...

In many industrial applications, the output of a process characterized by p variables that are measured simultaneously. Independent variables can be charted individually, but if the variables are ...

The following statements create a SAS data set named CIRC_ONE, which contains the number of failing circuits for 30 batches produced by the circuit manufacturing process introduced in the "Getting ...

Process inspection schemes using control charts with warning lines are considered and the properties for some schemes based on the observations from the last few samples are evaluated. Tables of ...

Measure: Only those characteristics that can be counted or measured are candidates for control. It is important to consider how measurement will be accomplished. Correct: When a process is out of ...
