Abstract: This paper presents a preliminary analysis of the system behavior
that works far from the thermodynamical equilibrium states in the environment
with limited resources. The examples of such systems are the real computer
systems. Nowadays in such systems the runoff characteristic of the information
flow is very turbulent in contradiction to the current existing laminar models.
These systems work under constant overload, which means a permanent
thermodynamical non-equilibrium (from the thermodynamical point of view). For
such a situation the classical approach to their modeling is still based on
Boltzmann-Gibbs (BG) thermodynamics,which is proper only for systems that are
in equilibriumstate (sometimes called thermostatic) or very close to it. The
changing number of tasks N in such systems and the limited resourcesK of the
environment cause its chaotic behavior and generate the dependencies that have
got a long-termproperty. Such processes degrade the system performance X and
elongate the response time R; in other words degrade the Quality of Service
(QoS). To understand the whole behavior of such systems one needs a proper
thermodynamical basis that seems to be the Tsallis formula of the non-extensive
entropy.
