“…If this condition was not included in the problem, it would be possible to extrapolate the dependences of costs in incomplete complexes on the number of disconnected components using standard methods of mathematical statistics. [14] But in connection with this condition, it was necessary to develop a mathematical apparatus for the implementation of the economic idea of extrapolation of dependencies. It synthesizes Lagrange least squares and least squares methods for a set of dependencies.…”

This study solves the most important economic problem of developing a method for calculating the cost of each type of product in complex and multi-product industries. The performed analysis of the current legislation and the methods used for calculating the cost has led to the conclusion that today the solution to this problem has no scientific justification. The authors carried out a systematic development of procedures that allow building a scientific idea using objective information. It is implemented in the study by means of appropriate techniques and the construction of an economic and mathematical model that allows the development of an instrumental apparatus for the implementation of the method. With its application, the problem of calculating the production cost of seven types of final products for a conditional technological scheme of integrated production was solved. The results are also compared with the cost calculation obtained by other methods. In addition, a graphical and matrix analysis of the calculation results was carried out. The obtained results of calculating the cost of the final product make it possible to evaluate this method as workable, and the algorithm for its construction - as using the entire array of initial objective information.
