Overhead costs include other management and maintenance costs that can be allocated directly to the project. In addition, this includes expenses for the maintenance, operation and repair of equipment, production tools and equipment, buildings, structures, etc.

Overhead costs account from 30% to 90% of the amount of base and additional salary of employees.

Overhead is calculated according to the formula:

where,

^Сov

^^kov^^(Wbase

 W_add)

(4.15)

k_ov– overhead rate.

Table 4.15 Overhead

	Project leader	Executor
Overhead rate	40%
Salary, rubles	94240.60	79974.03
Overhead, rubles	37696.24	31989.61
Total, rubles		69685.85

Other direct costs

Energy costs for equipment are calculated by the formula:

^С^^P_el^^Р^^F_eq,

(4.16)

where,

el
_P− power rates (5.8 rubles per 1 kWh);

Р− power of equipment, kW;

^Feq

− equipment usage time, hours.

Formation of budget costs

The calculated cost of research is the basis for budgeting project

costs.

Determining the budget for the scientific research is given in the

Evaluation of the comparative effectiveness of the project

Determination of efficiency is based on the calculation of the integral indicator of the effectiveness of scientific research. Its finding is associated with the definition of two weighted average values: financial efficiency and resource efficiency.

The integral indicator of the financial efficiency of a scientific study is obtained in the course of estimating the budget for the costs of

three (or more) variants of the execution of a scientific study. For this, the largest integral indicator of the implementation of the technical problem is taken as the calculation base (as the denominator), with which the financial values for all the options are correlated.

The integral financial measure of development is defined as:

(4.17)

where,
– integral financial measure of development;

C_i– the cost of the

i-th version;

C_max – the maximum cost of execution of a research project (including analogues).

As an analogue, the method of temperature stabilization of a radiation detector is done by placing the detector in the climatic chamber and measuring the dose rate and count rate of a gamma ray source.

The integral financial measure of development can be calculated

as:

(4.18)

C_i – the cost of the research work using gamma background radiation = 325707.14

And C_max – the maximum cost of execution of research project using a gamma radioactive source = 400,000.00

????^???? = 1 (4.23)

The obtained value of the integral financial measure of development reflects the corresponding numerical increase in the budget of development costs in times (the value is greater than one), or the corresponding numerical reduction in the cost of development in times (the value is less than one, but greater than zero).
Since the development has one performance, then = 1.

The integral indicator of the resource efficiency of the variants of the research object can be determined as follows:
