The rapid growth of the COVID-19 pandemic in the world and the importance of controlling it in all regions have made managing this crisis a great challenge for all countries. In addition to imposing various monetary costs on countries, this pandemic has left many serious damages and casualties. Proper control of this crisis will provide better medical services. Controlling travel and tourists in this crisis is also an effective factor. Hence, the proposed model wants to control the crisis by controlling the volume of incoming tourists to each city and region by closing the entry points of that region, which reduces the inpatients. The proposed multi-objective model is designed to aim at minimizing total costs, minimizing the tourist patients, and maximizing the number of city patients. The Improved Multi-choice Goal programming (IMCGP) method has been used to solve the multi-objective problem. The model examines the results by considering a case study. Sensitivity analyses and managerial insight are also provided. According to the results obtained from the model and case study, two medical centers with the capacity of 300 and 700 should be opened if the entry points are not closed.

COVID-19 大流行病在世界范围内的快速增长以及在所有地区控制它的重要性使应对这场危机成为所有国家面临的巨大挑战。除了给各国带来各种货币成本外，这场大流行病还造成了许多严重的损失和人员伤亡。妥善控制这场危机将提供更好的医疗服务。在这场危机中控制旅行和游客也是一个有效因素。因此，所提出的模型希望通过关闭该地区的入境点来控制进入每个城市和地区的游客量，从而减少住院病人，从而控制危机。所提出的多目标模型旨在最小化总成本、最小化旅游患者和最大化城市患者的数量。改进的多选择目标规划（IMCGP）方法已被用于解决多目标问题。该模型通过考虑案例研究来检查结果。还提供了敏感性分析和管理见解。根据模型和案例研究获得的结果，如果不关闭入口点，应该开设两个容量分别为 300 人和 700 人的医疗中心。
