  Currently, the increase in financial returns from economic operations is
constrained in view of the lack of a single efficiency criterion, which allows
uniquely identify the business operation by their main feature - the
possibility of obtaining the maximum value added (profit). One of the main
scientific steps on the way to obtaining the formula of efficiency is
developing the "resource intensity" indicator. The development of this
indicator was based on the model of the deployed operation and determination of
the time of the actual completion of the target operation, which does not
coincide with the traditional notion of the time of completion of economic
operations. For processes with distributed parameters, an expression for
determining the resource intensity using numerical methods was derived. For
economic operations, which can be reduced to simple operations, an analytical
expression of resource intensity was obtained. Using mathematical modeling
methods it was revealed that in the case of a fixed value of expert (cost)
estimate of output products of the operation, the minimum resource intensity of
the operation indicates a maximum efficiency operation with respect to the
target product of the operation. Development of the resource intensity of
economic operations is the final step towards the development of cybernetic
(interdisciplinary) efficiency indicator that allows to maximize the value
added (profit) of economic operations.
