Providing patient-centered centers, which is cost-effectiveness, as well as, quality health care is a big task for health care planners in every country. It is obvious that the management of unforeseen events, including infectious diseases, has a significant role in reducing human casualties and material costs during crises. In this essay, a mathematical model for locating hospitals equipped with corona virus, support centers and warehouses to equip support centers is investigated. This is necessary in cases of increasing number of patients, who usually face a lack of resources or medical staff in hospitals. Therefore, temporary emergency centers near hospitals have been established with the aim of improving hospital performance, reducing congestion in hospitals and taking into account the wellbeing of applicants, and patients who are in short supply in hospitals are assigned to the nearest center to hospitals. Previous research on the location of these centers is limited into certainty, but in the forthcoming essay, due to the uncertain nature of the post-crisis situation, the amount of demand is considered uncertain. District 4 of Tehran province is considered as a case study in this study. The results of solving the developed model show that with the aim of minimizing the fixed costs of equipping centers, the distance between hospitals and support centers, the distance between support centers and warehouse and also the cost of non-coverage of demand, when the number of demand centers is 5 is optimal. It has the highest performance, which means that costs are minimized, the implementation time of the solution is reduced to a minimum, and all areas are covered. . Also, with the increase in the capacity of resources (beds, ventilators, etc.) and medical personnel, the costs of non-coverage are declining. Also, by comparing the two mentioned parameters, it can be concluded that the effect of medical staff capacity on non-coverage costs is more than resource capacity
