Relation between measurable indicators of quality features of different nature and their assessment to scale dimensionless

Abstract

The article analyzes the existing types of relationships between the measured indicators of quality
of objects of different nature and their assessment on a dimensionless scale and show their advantages and
disadvantages. Detected number of features considered dependencies, including the fact that they do not
contain any parameters, so there is no need to evaluate them. In addition, using the principle of symmetry,
it is possible to obtain a number of intermediate dependencies, that allows you to optimize the quality
requirements of the object. It also shows that all curves have an exponential form and never cross the value
of "unit" and cross the value “zero” on the x-axis, which corresponds to the quality of ideology.
A new kind of dependency, which takes into account only the maximum and minimum
allowable value of an indicator of quality of the object and can be used to assess the quality of
products, and to evaluate the quality of processes and services. By changing the shape, you can
change the slope of addiction, it does not change the inflection point, which is fixed in the middle of
the tolerance on the quality score. This type of dependence can be considered universal.
