  The model of the physical system with discrete interactions is based on the
postulates that
  (i) parameters of the physical system are defined in process of its
interaction;
  (ii) the process of interaction is discrete.
  Consequently ordering of the events in the system is not automatically
implied based on the values of time, but must be specified explicitly. This
suggests the specific logic of events as well as complex character of the
function, which describes stochastic behavior of the system, hence the
parameters of the system are defined by Hermitian operators in the Hilbert
space of functions.
  The model gives an essential way to introduce the basic notions and obtain
the results of the quantum theory, to derive the meaning of the main physical
parameters, such as momentum or electric charge. Based on the proposed
postulates, Schrodinger equation for the particle is deduced in a way similar
to inferring of Smoluchowski equation in the classical statistical mechanics.
  Similarly, the equations of motion of linear fields are established by
considering Smoluchowski-type equations for amplitudes of harmonics.
  The concept of discrete interaction gives a way to de-couple the object of
experiment and a testing device (the traditional source of controversy in
quantum theory), though at expense of limitation of the principle of locality.
