Few simple rules to fix the dynamics of classical systems using   operators
  We show how to use operators in the description of {\em exchanging processes} often taking place in (complex) classical systems. In particular, we propose a set of rules giving rise to an {\em hamiltonian} operator for such a system $\Sc$, which can be used to deduce the dynamics of $\Sc$.
