1. Stages of the formation of qualimetry
Measuring and evaluating quality has always been one of the most important
most directions in the sphere of industrial activity.
The first known cases of product quality evaluation include
by the 15th century BC Then the potters of Crete labeled
their products with a special sign testifying to the
and the high quality of their products. It was a score
quality on the so-called "scale of names", or on "ad-
resale scale. Brand names as well as other quality marks
and now serve as a guideline, an indicative sign of quality
products. Later, as a kind of expert method
assessing product quality, used a method based
on the generalized experience of consumers, - the method of "collective
wisdom. " The oldest example of expert quality assessment
is a wine tasting.
The development of international trade required classifications
product quality categories, and for that
It was not only to measure individual product properties, but also
Honorly evaluate its quality on the aggregate of all major
consumer properties. In this regard, in Europe and the United States,

In the years of the twentieth century, in the USSR and in other countries, methods of quantitative
assessment of the quality of goods successfully developed and
enjoyed in practice. For example, in 1922, P. Bridgeman
He proposed a method of reducing to one indicator of several
qualitative estimates of various parameters characterizing
quality. In 1928, M. Aranovich solved the same problem. At the same
time P. Florensky proposed new ways of processing
ki data in the quantitative assessment of product quality.

During the years of the “cold war” of two social systems (capital

political but also competitive economic struggle of various
countries and firms, the victory in which depended largely on

2. Qualimetry as an independent science
The term "qualimetry" comes from the roots of two words:
“Quali” - quality and “metry” - measurement and quantitative
evaluation of something.
It is known that quality is the most common scientific category.
a mountain whose meaning expresses a certainty of the essence or
essential certainty of any object. Quality of character
is implemented by the cumulative assessment of all its properties, characteristics and attitudes
with other objects.
Qualimetry is an independent science that is part of the

The subject of qualimetry is quality assessment in the number

The qualimetry structure consists of three parts:
1 - general qualimetry or general theory of qualimetry,
which addresses issues and questions as well as methods
measurement and evaluation of qualities;
2 - special qualimetry of large groups (class
sov) objects, for example, qualimetry of products, processes
(in a broad sense), services, social security,
tania and so on down to the quality of life of people;
3 - subject qualimetry of certain types of products,
processes or services, such as qualimetry engineering
products (definition of the technical level of machines),
Limetry of construction sites, qualimetry of petroleum products,
qualimetry of electricity, qualimetry of food
var, qualimetry production processes, qualimetry
labor, qualimetry education, etc. etc.
3. Basic principles and objectives of qualimetry
Qualimetry has its own methodological principles:
1. Priority in choosing determinative indicators for evaluation
product quality is always on the consumer side. Product

Consumer indicators are preferred.

2. Qualimetric assessment of product quality can not be
obtained without a reference for comparison - without basic
values of indicators of defining properties and quality in order to
scrap.
3. Indicator of any level of generalization, except the lowest
(source) level is predetermined by the corresponding
indicators of the previous hierarchical level. Under
the lowest hierarchical level of indicators follows

7. The quality of the whole object (in particular, the products or
process) due to the quality of its components.
8. In the quantitative assessment of quality, especially by

words and, therefore, duplicate indicators of one

and product quality assessment. And it was quite natural

scientific and technical, popular science and even social
political literature often addresses the problems of com-

Modern methods of quality assessment (despite
that the object of their assessment is the most heterogeneous) are characterized

in terms of theoretical qualimetry, these techniques are one

Thus, we can assume that:

- the algorithm of these methods and the principles on which they base
they are practically the same as those adopted
in theoretical qualimetry;
- the scope of many of these methods, for example,

Expanding the scope of qualimetry will help to bring scientific
base for a whole range of methods for solving evaluation problems

products;
2) assessment of the quality of manufactured products;
3) assessment of the competitiveness of a product or company;

5) evaluation of the effectiveness of advertising and PR;
6) determining various ratings;
