Abstract
For determining ways of company
development, ensuring the growth of profit in manufacture and
sales of certain products, it has been proposed to use an
algorithm of constructing a problem being inverse to primaldual one, for minimization of the project costs. The primal and
the inverse problems contribute to improving the efficiency of
calculation when determining approaches for minimization of
costs. This pair of problems is mutually conjugate. The proposed
rigorous approach to obtaining the algorithm of constructing a
dual problem is based on the following statement: a problem
being inverse to a dual one is a primal (original) problem. The
authors have proposed and rigorously proven the algorithm of a
general approach to the construction of conjugate problem pairs.
Formalization of the algorithm developed allows obtaining
easily correct pairs of known dual problems. This permitted
proposing and proving the truth of the algorithm of constructing
a dual problem for the arbitrary form of a primal problem representation.
