Abstract

A mandatory item of the standard terms of reference for the implementation of scientific and research work (SRW) performing is the “Technical and economic requirements” item, which, in particular:

- establishes the limit value of the research cost;

- determins the stage at which technical and economic justification of the research continuation practicality is carried out;

- establishes the need to determine the estimated costs of implementing the results of research.

Each of items specified in the requirements is associated with evaluation of the technical complexity and efficiency of the designed information transmission radio systems (ITRS). Currently, the most common industry performance indicator of RW is a generalized indicator of the effect/cost. The research effectiveness justification is all the more necessary at the stage of determining the research contractor by the customer.

As a rule, the method of comparing some of the most important from the contractor’s view point characteristics of the designed ITRS with similar characteristics of a prototype is employed while technical effect assessing. With account for the dynamics of the characteristics being compared an inference is being drawn that the SRW performing will lead to the positive effect, and a new more efficient ITRS will be developed while the results of the experimental and development effort implementation. Besides certain voluntarism while the prototype selection and a set of compared characteristics, the drawback of this method consists in complexity of technical efficiency estimation, which may be explained by the necessity of vector indicator application, accounting for the values of individual characteristics.

The purpose of this article consists in developing a methodology for effect/cost calculating, based on the analysis of relative values of ITRS the main technical characteristics, formed by comparing these characteristics values with tmaximum potential values of the reference ITRS.

The relative indicator of technical efficiency, characterizing the effect of the R&D products being developed while the SRW performing, and economic efficiency indicator, characterizing increase of technical effectiveness per unit of the investment in the SRW under development, were suggested for estimating the effect/cost indicator widely used for SRW performing efficiency.

Rejection of subjective indicators of the preceding ITRS samples, which are being selected as prototypes at present, may be assigned to the advantages of the suggested indicator.
