The simulation (computer modeling) is used at many fields as the science method and
for completing of simulator on which medical doctors makes his praxis training. The simulation
software makes easy to compose simulation model on computer. The article presents
software CDCSIS using on the examples: the simulation program for gripe infection model
(time continuous process), the simulation of hospital beds occupation (discrete process –
the model states are changed at the finite time points) and the computing of spine bend
under scoliosis loading as example of process which change its states continuous in time
and changes its structure at finite time points (combined discrete continuous simulation).
The article purpose is to show how a simulation program compilation is easy.

Simulation (computer modeling) is
a method for solving the tasks changing
their states in time (dynamic model). The
model of real experiments is composed
on a computer and the course of model
behavior is compared with the real experiment
(real process course). Parameters
and model structure are changes to be the
model behavior the same with observed
real process (model verification). The
result is recognition of the real process
rightfulness and further the approved computer
model can be used for real authenticity
prognosis. The simulation software
makes possible easy simulation models
compilation. The simulation methods are
used at many science fields in this time.
The simulation is used at medicine praxis
for simulators compare for example for
surgical execution training.
The simulation software is divided
according its using in follow way:
1. Continuous simulation makes possible
to compare a model changing their states
continuous in time if the model do
not change its structure, for example
software MATLAB and SIMULING. The
differential equation solving is typical
for the continuous simulation.
2. Discrete simulation makes possible
to compare a model of system witch
