خلاصه:Abstract
Reliability of manufacturing processes can be obtained from daily production data when process failure criteria are established. Results of the analysis are displayed on Weibull probability plots. Losses are categorized and identified for corrective action based on a demonstrated production criterion, which gives a point estimate for the daily production value. Concepts from six-sigma methodology are used to establish the effective nameplate capacity rating for the process. The differences between the nameplate rating and the demonstrated production are labeled as efficiency and utilization losses.
