2014-9-29  Applying control charts successfully to batch processes requires the recognition of some distinguishing features of batch processing versus single‐unit processing. Traditional Shewhart‐type charts can be modified for use in batch‐processing practitioners of statistical process control (SPC); however, entirely different control chart methods and practices will often be required.

Model predictive control for batch processes: Ensuring ...

2014-1-1  The primary control objective in batch processes is to reach a specified product quality at the point of batch termination. Accurately controlling the final quality of a batch process is challenging in that physical measurements of the quality parameters that can be used to predict the final quality are often not available on-line [1] , [2] .

Analysis of Batch Processes using a Batch Means Chart

Control charts can be applied to batch processes. However, as in multi - stream processes, the traditional X-bar chart cannot be used as you might expect. When you select subgroups for the X-bar chart, subgroup observations collected from within the batch provide an estimate of the within batch variation, but do not provide a good estimate of ...

Introduction - Control of Batch Processes - Wiley

2014-5-30  The capabilities required of the control system vary greatly with the nature of the batch process, with cyclical batch being the simplest to control and flexible batch the most demanding. In the 1950s, most of the process automation equipment was pneumatic, with “analog signal” meaning a 3–15 psi pneumatic signal.
