Abstrak

The article deals with the main indicators of efficiency of project solution variants; the principles of variability, which provide the possibility of comparative evaluation of variants, the principles of stages in decision-making.

Key words: Choice of variant, modified, integral effect, efficiency of variants, project decision.

Selection of the railway direction variant and its parameters is carried out at the early stages of the design preparation of construction. The comparison of options and decision-making on further development of one of the options is carried out according to the following scheme [1].

At first, the most effective variant is selected according to the indicators of comparative economic efficiency, which are: comparative integral effect, reduced (modified - in case of taking into account the share of tax deductions from profit) construction and operating costs, payback period of additional investments, efficiency coefficient of additional investments [1], [2].

Then the selected variant is evaluated by the indicators of overall economic efficiency, the main of which are: net discounted income (integral effect of investments), payback period of investments, profitability index (index of profitability of investments) and internal rate of return (rate of return on investments).

If the selected variant meets the requirements of the overall economic efficiency of investments and provides the rate of return on investments and the investment return period required by the investor, the commercial efficiency indicators for this variant are evaluated by determining the real money flows on investment, operational and financial activities of the enterprise (projected railway) and calculating the current and accumulative balance, with positive values of which in any time interval the selected variant is recognised. If the balance is negative, the possibility of attracting additional funds by the investor is considered [1], [2].

In the scheme considered, the main indicators of the effectiveness of the project solution options are cost (monetary), which is generally recognised, despite the known shortcomings of these indicators [2].

The principle of variability is applied in railway design, which provides the possibility of comparative (competitive) evaluation of options. The fundamental difference between the variants is explained by the different objectives set by the designer in a particular task (and these objectives are most often multidirectional).
