One of the key ideas in lean manufacturing is that defects should be detected as early as possible. Efforts to control manufacturing processes so that issues can be detected before defects occur ...
Today's defect rate was 3%. Is that high, or is it just normal?” Even if you record the daily defect rate, you may find ...
Control charts have been widely used for monitoring production processes and identifying assignable causes of variability. Many papers investigate the application of control charts in different ...
This article discusses how quality control tools can be used in the garment industry to improve the quality of production processes and products. It provides an overview of the different quality ...
The two basic modes of process control are sequential control, or On/Off action, and continuous control action. This chapter deals with process control, discussing both sequential and continuous ...
Machines and processes are controlled using many strategies, from simple ladder logic to custom algorithms for specialized process control, but proportional-integral-derivative (PID) is the most ...
I recently surveyed the on-site development of the control system for a large concentrated solar power station. This “first of a kind” facility offered many control challenges, such as balancing heat ...
When it comes to process-control systems, reliability is crucial and failure can be costly or dangerous. A combination of good design practices, component selection, and testing can enhance ...
