Editing Stochastic (section)

== Manufacturing ==
Manufacturing processes are assumed to be [[stochastic process]]es.  This assumption is largely valid for either continuous or batch manufacturing processes.  Testing and monitoring of the process is recorded using a [[process control]] chart which plots a given process control parameter over time.  Typically a dozen or many more parameters will be tracked simultaneously.  Statistical models are used to define limit lines which define when corrective actions must be taken to bring the process back to its intended operational window.

This same approach is used in the service industry where parameters are replaced by processes related to service level agreements.
