Development of recommendations for implementing simulation modeling and blockchain technologies in certification system of the radio electronic industrial production

The most topical task is to increase competitiveness of industrial products, which is closely connected to permanently increasing competition in the international market and necessity for enterprises to comply with the requirements of regulatory and technical documentation. Certification is the main tool in ensuring high quality products of industrial enterprises. This work is devoted to elaboration of recommendations for improving certification system on the example of ensuring compliance of radio-electronic industrial products with requirements of the Eurasian Economic Union technical regulations on the technical means electromagnetic compatibility (EMC). Under conditions of the digital economy rise and development, it is advisable for manufacturers of industrial products to introduce simulation modeling technologies to create digital twins of their products and to conduct tests for compliance with the EMC requirements at the design stage to ensure that certification tests are passed in laboratories from the first. The authors estimated the main risks arising from simulating this type of tests using the “probability – damage” matrix; and also, a number of measures is proposed to minimize the risks of test results reliability reduction for digital twins. It is advisable to thoroughly work out the radio-electronic product circuit and electrodynamic model to ensure the input data sufficiency for software and hardware complex in implementation of the digital tests. Besides, special attention should be paid to the rational selection of computing devices, workplaces, test modes and necessary parameters of radio-electronic industrial products to be analyzed. After completing digital testing during the design phase, it is rational to monitor the results of certification tests to collect information and improve digital twins. To achieve reliability and transparency of the certification test results, the authors propose to apply an algorithm based on the blockchain technology and characterized by introduction of a unit to automatically register the test results, encode and place them in a secure database accessible to a number of users by specially formulated requests, which are protected by a specialized private key.
