Comparison of methods for regulating processes based on measuring control information on an alternative basis by the narrowed tolerance

The method of statistical process control using process parameters estimates based on the data by attributes, counting falls of the quality characteristic beyond the narrowed (in relation to the documentation requirements) specification interval, is proposed. Pittman-type estimates, which are researched by the author previously, are used. The results of simulation confirming that the proposed method is more efficient than the earlier known one are given.
