COVID-19 salgınının, İtalya örneğine dayanan sosyal uzaklaştırma önlemleri ile geri adımlamalı kontrol metodu kullanılarak hastanede yatması gereken hasta sayısının, mevcut yatak kapasitesini geçmeyecek şekilde kontrolü ele alınmıştır. Sosyal mesafe önlemleri, sokağa çıkma yasağı gibi önlemler ile devletler ve yerel idareler salgının yayılmasını önlemek istemektedir. Salgının tamamen yayılmasını önlemek ancak mutlak bir tecrit ile olabilecekken, bu çözüm sosyal hayatın ve ekonominin aşırı derecede olumsuz etkilenmesine sebep verecektir. Bu nedenle, her bir ülke/şehir, en azından kendi yatak kapasitesini aşmayacak şekilde salgını kontrol altına almak isteyecektir. Bu makaledeki bulgular, şehir yöneticilerine veyahut genel idarecilere, salgını yönetmek için referans teşkil edecektir. İnsanların salgınla olan alakasına göre, bu makalede toplum sekiz bölüme ayrılmıştır. Bunlarda bir gurup ise tedavisi zaruri olmuş guruptur. Geri adımlamalı denetleyici vasıtasıyla, hastaneye yatması gereken hasta sayısının, mevcut yatak kapasitesinden az değerde tutulduğu ispatlanmıştır. Benzetim sonuçları da iddia edilen kontrolcünün sorunsuz çalıştığını göstermektedir.

Back-stepping control of Covid-19 spread not to exceed hospital capacity

Öz

In this paper, controlling the number of patients who are required to stay in hospitals due to covid-19 through back-stepping controller is considered by using data from Italy.. States and local administrations want to prevent the spread of the outbreak, with measures such as social distance measures, curfews. Even though the absolute control of the pandemic can be reached through absolute isolation, this solution will cause excessive negative effects on social life and economy. Therefore, each country/city would like to control the outbreak, at least not exceeding its bed capacity. The results of this article has potential of serving as a reference for city administrators or general administrators to manage the outbreak. Based on the current health condition of the people due to the epidemic, society is divided into eight sections in this article. One of these eight population groups is the ones whose hospital treatment is mandatory. With the back-stepping controller, it is proven that the number of patients who need to be hospitalized can be kept below the current bed capacity. Simulation results also show that the proposed controller is effectively controls the patients those need to be hospitalized.
