Query: Creation and Verification of Digital Twins in Cloud Production   This article discusses the use of digital twins for products made of polymer
composite materials. The design of new products from polymer composite
materials, both within the framework of the traditional and new direction of
cloud production, requires the need to calculate the physical and mechanical
characteristics of the product at the design stage. Carrying out full-scale
tests increases greatly the cost and slows down the production. It requires the
manufacture of a prototype of the product. The use of existing development
tools does not always provide the required characteristics. To solve this
problem, it is proposed to use a digital twin, which will not only solve the
problem, but will also help to move to cloud production and the development of
the Industry 4.0 direction. Thus, a new problem arises - how to create digital
twins of products from polymer composite materials. The analysis makes it
possible to conclude that the traditional methods of mathematical physics are
not suitable for the solution of this problem, since the twins obtained with
their help do not have any properties of adaptability. To solve the problem, it
is proposed to use deep neural networks one of the most powerful methods of
machine learning. This will make it possible to obtain digital twins of
products made of polymer composite materials that can adapt to changes in the
model, environmental conditions and adapt to changes in the indicators of
sensors and transducers installed on the product.
