Applications of operational approach to evaluation of projects of economic systems development

The paper proposes a technique of obtaining the investment project optimal cost for the development of economic systems. The considered systems are described by multi-step multicriteria linear programming problems with discounting coefficients in the objective functions. The proposed technique is based on the operator which is equivalent to the $z$-transform for finite time interval. Application of the proposed technique allows one to classify the projects as unsuitable or potentially effective during the preliminary analysis stage.
