The article considers a solution for an
economy prognosis formation task in
different industries and service sector. In
addition, it contains a review of
mechanism of an intersectoral balance and
theoretical components of V.V. Leontief
linear economic model of intersectoral
balance. Premises of mathematiceconomical
apparatus usage and practical
usage in economy planning of many world
countries and also results of this apparatus
working making that countries’ economic
condition “almost balanced” are studied.
Inferences of “Input–Output” method
significance in economy planning for
company groups and country in general are
made in this article too.
Solution of program product for
calculations and analysis development
necessity is substantiated. In this program,
output of reports is envisaged. Practical
example of intersectoral balance task with
the developed program is given in article
and accuracy of calculations is approved.
Program product structure and
development tools are described. The
program can be used as a tutorial for
students studying on economical directions
for economic indicators calculation
experience gaining
In this article, we have presented the study and
implementation of the physical model of
motion of two coupled pendulums with use of
numerical methods. When building the model
we were using the method of Euler solutions of
differential equations, which displays
pendulums visual motion, as well as building
graphics of functions of speed, angle and
acceleration depending on time with high
reliability. We have generated equation of
motion for generalized coordinates for the first
and second mathematical pendulum. The
generated application implements a physical
model of a double mathematical pendulum,
commit sustained oscillations with the ability
to change the basic parameters: deflection
angle, speed, mass and length of the rod in C++
language by programming environment
“Embarcadero RAD Studio”. This application
can be used as a model of a double
mathematical pendulum in the study of
oscillations, as a methodical manual and a
virtual laboratory in physics, informatics and
programming classes – for demonstration,
study and create applications in the objectoriented
C++ programming language
