We present a simple and systematic method to calculate phase diagrams of random Ising models. It applies to a wide class of systems in which, however, randomness has to be described by discrete random variables. We calculated, at different orders of approximation, various quantities like critical temperatures and percolation thresholds in good agreement with exact known results.Nous présentons une méthode simple et systématique permettant de calculer des diagrammes de phase de modèles d'Ising aléatoires. Elle s'applique à une vaste classe de systèmes dans lesquels, cependant, il est nécessaire que le désordre puisse être décrit par des variables aléatoires discrètes. Nous avons calculé à différents ordres d'approximation diverses grandeurs ...
