This work aims to identify prioritization models in humanitarian operations according to a systematic review of the literature identifying models, object of prioritization and criteria. Keywords: prioritization model, disaster, humanitarian logistics. INTRODUCTION According to the International Federation of the Red Cross, disasters are sudden and calamitous events that disrupt the normal functioning of a society or community, causing economic, human, environmental or material losses which exceed the community's resilience (IFRC, 2012). Data collected by the Centre for Research on the Epidemiology of Disasters (CRED) and consolidated in the database Emergency Events Database (EM-DAT) shows that, between 1990 and 2014, 9,336 disasters were recorded worldwide with 2.3 million deaths during this period and about 209 million affected annually. The types of disasters with most affected people were floods and droughts (CRED, 2015). Besides the characterization by event type, a disaster can be classified as having a rapid onset - such as earthquakes, hurricanes and terrorist attacks - or slow onset - as famine, drought and refugee crisis (Van Wassenhove, 2006); special tools are needed for each context as preparation time and strategies of response are different for each type of disaster and onset occurrence. In addition, disasters are divided into four phases: mitigation, preparedness, response and reconstruction. The goal of the mitigation phase is to prevent the occurrence or, at least, to
