Our research is based on the well-known encyclopedic definitions of the term
modernization, emphasizing the modern constructive refinement of products. We have
shown that the modernization of industrial high-tech products is a complex scientific
and production problem. It requires a system solution taking into account a variety
of risks, factors and conditions, including unification.
We have examined the content of key stages of modernization:
(a) formation of requirements for modernized products; (b) determination of the
functional and operational-technical characteristics’ level conformity for existing
products with the requirements imposed on them; (c) formation of possible options
for the modernization of products to meet specified requirements; (d) determination
of modernization type taking into account the state of products and directions
of unification for each modernization type; (e) technical and economic assessment
of modernization options by the criterion of efficiency — costs and justification
for choosing a rational option.
We have proposed a method of economic evaluating the unification measures
effectiveness, based on a structural analysis of the costs of modernization and
establishment of those components that are most dependent on the ratio of new,
including the original, and unified components. The essence of the proposed method
consists in a comparative evaluation of the costs of development work for modernization
using only original and with the joint use of original and unified components.
In conclusion, the maximum joint use of unification and modernization potentials
becomes a priority strategy for improving and developing modern technological and
technical systems. Modernization works should be carried out systematically on
the basis of the methodology of program-target planning, taking into account the
interrelation of existing and upgraded products, as well as the results of detailed technical
and economic analysis of the whole set of measures for unification for a long period.
