Oung individuals, adults and also the elderly. The severity of COVID-19 disease roughly corresponds to these three groups [102]: young people today who are infected typically possess a mild kind of the disease, adults usually have a far more really serious kind and correspond towards the group of severe patients, and elderly men and women represent the majority of critical cases. The age membership function presented in Figure 4 shows that individuals between 30 and 60 years old are much more vulnerable than the young people but significantly less than the older group. Secondly, the membership function in between 30 and 60 has been selected linear. This fuzzy membership function is just not particular only for the islands of Guadeloupe but may be generalized anyplace in the world and it is determined by the observations made.Biology 2021, 10,6 of0ageFigure 4. Fuzzy membership function of Hospitalization compartment in Nemadectin Cancer accordance with age (in years).Certainly, the second risk issue, obesity, features a membership function equivalent for the age, but we made a difference amongst females and guys [28]. Obesity risk can lead to the essential kind of COVID-19, even for young individuals [135]. The health-related information [28] for Guadeloupe archipelago offered facts on the α-Carotene Cancer distribution of obesity by age and sex. We model this danger of vital type linked to obesity (top to hospitalization) as a membership function which considers also the age for men and for women. The proposed fuzzyfication is presented in Figure 5.girls men0ageFigure 5. Fuzzy membership function of Hospitalization compartment in terms of obesity for males and females.In accordance with the healthcare information, the proportion of obese women is about double that of men amongst adults, which implies a greater danger. The proportion of obese young people today is low for both sexes. Concerning the elderly, majority of men and women are obese, irrespective of gender. This aspect increases the danger and explains the shape on the membership functions described in the figure above. From these two membership functions of men and females for obesity, we viewed as a new observation obtained by aggregating the values of those two functions. As outlined by our information related towards the ratio involving males and females in hospital as a result of COVID19 [27,30,31], we defined some weights that ponder these two membership functions. So as to respect the ratio of hospitalizations as a result of COVID-19 in Guadeloupe [27], we make use of the following weighted typical: 0.six f guys + 0.four f women (3)Biology 2021, ten,7 ofwhere f guys is definitely the fuzzy membership function for obesity of men and f females may be the fuzzy membership function for obesity of girls. We thus have only a single worth for the risk of hospitalization in relation to obesity. 3.5. Fusion of Membership Functions To estimate the hospitalization price, we’ve merged the two fuzzy functions corresponding respectively towards the danger connected with age and also the danger connected with obesity. The merger is carried out with distinctive varieties of aggregation operators: the arithmetic mean the triple operator [32] the arithmetic imply can be a averaging operator: these operators give a value involving the maximum as well as the minimum. It is a compromise. the triple operator is a complete reinforced operator [33,34]: these operators are each positively reinforced and negatively reinforced. They favor extremes and accentuate differentiation.These two operators belong to two distinctive categories [33]:In other words, the imply models a moderation plus a balance of obesity and age components, while if these two components have robust values, the tripl.
