  In this paper we try to define the difference between hierarchical
organization and self-organization. Organization is defined as a structure with
a function. So we can define the difference between hierarchical organization
and self-organization both on the structure as on the function. In the next two
chapters these two definitions are given. For the structure we will use some
existing definitions in graph theory, for the function we will use existing
theory on (self-)organization. In the third chapter we will look how these two
definitions agree. Finally we give a conclusion.
