Manufacturing Statistical Control (Allied Signal)

Allied manufactured chemicals meeting strict customer specifications. Because of the hundreds of variables and the tight tolerance measurements, Allied wanted to automate the manufacturing process control reporting, improve quality, and expand capacity.

The system accumulated data for multiple manufacturing processes. The system used statistical formulas to produce mean and range charts (statistical control graphs) on any one or more of the hundreds of measurements. This required working with engineers and statisticians to convert the complicated formulas into computer code. Printed reports and graphs are used in proposals as well as documentation to deliveries.
