MONITORING VARIABILITAS DARI PROSES SHORT DAN LONG RUN

Abstract

One of the problems in the quality improvement is variability monitoring, in such a way so it remains on the threshold. The
main problem in the implementation of process variability monitoring is the parameter estimation before the process
production is run. . In the short run process or long run process on start up stage the problem is difficult to handle. This
paper discusses an approach, which enables to do the process variability monitoring for short or long run processes,
without historical data for parameter estimation. An illustration of comparison clarifies the mechanism of our discussion.
