This presentation will explore default and edited pchart and xchart examples using health services research data; including the syntax for creating these graphs. Graphic elements include customized axis labels, text, colors, lines, notes, fonts, and titles. Under this approach STATA can replace ...
Examples include: Should we produce this part internally or outsource it to a supplier? Should we transfer work from one supplier to another? Should we purchase a new machine tool? Utilizing the millions of measurements in Net-Inspect's web based SPC software solution, our experts developed an...
Statistical Process Control (SPC) is a methodology and set of tools used in quality management and manufacturing to monitor, control, and improve processes by using statistical techniques. The primary objective of SPC is to ensure that a process operates consistently and produces products or services...
This paper explores the effects and benefits of both autocorrelation and cross-correlation in controlling manufacturing processes using case examples from automotive manufacturing processes. The author shows that making use of the correlation structure in the measurements can greatly reduce variability in ...
