| Summary: | A fundamental property of the technological process is - Stability. The information obtained as
a result of the statistical analysis of accuracy and stability of the technological process can be used as an
argument for a regulator in the automatic-control system to synthesize the corresponding control action.
The stability of the technological process as a probabilistic characteristic reflecting the quality of its course
has been used for a long time and all this indicator was determined in different ways. The article provides
an overview of the various approaches of various authors to the definition of stability. In addition, the
paper analyzes the advantages and disadvantages of such approaches, as well as proposes a method based
on the ratio of the process dispersions over the sliding time intervals. The importance of introducing the
function of managing the stability of a technological system is difficult to overestimate, since the
widespread introduction of the quality control system of Hazard Analysis and Critical Control Points
(HACCP) does not allow considering the possibility of managing the quality of technological processes
over time, but only statically, which does not guarantee the production of quality products. |
