When a natural disaster occurs, such as an earthquake, flood, etc., there are groups of people who cannot cope alone and need additional help. One such group is diabetics. In addition to the main disease, they often have various complications. Even if a diabetic is in good physical condition and able to evacuate the disaster site by himself, he needs additional care, such as regular insulin and other medications. In this research, we focus on the evacuation of diabetics after an earthquake. We propose a model of evacuation, base on Generalized Net (GN) aparatus. The goal is to be able to play out a variety of scenarios and make the most appropriate decision given the specific situation. The purpose of the model is to support the local authorities for preliminary preparation and training of the staff who will provide assistance, as well as for a quick and adequate response after the occurrence of an earthquake.
