In this paper, we study two kinds of combinatorialobjects, generalized integer partitions and tilings of 2D-gons(hexagons, octagons, decagons, etc.).We show that the sets of partitions,ordered with a simple dynamics, have the distributive lattice structure.Likewise, we show that the set of tilings of a 2D-gonis the disjoint union of distributivelattices which we describe.We also discuss the special case of linear integerpartitions, for which other dynamical models exist.
