Monitoring a Random‐input Production Model

Abstract

Considers an input‐output production model with random‐input variables. Presents statistical control charts to monitor the output quality, the random‐input variables, and the stability of the production process. These monitoring procedures serve the purposes of acceptance inspection of product output, acceptance inspection of input materials, and production process control. Gives an example in cotton spinning to illustrate the control of a random‐input production process.
