Oung men and women, adults along with the elderly. The severity of COVID-19 disease roughly corresponds to these three groups [102]: young folks that are infected frequently have a mild type on the illness, adults typically possess a much more serious kind and correspond towards the group of serious sufferers, and elderly folks represent the majority of vital circumstances. The age membership function presented in Figure four shows that Activin A Protein Source people amongst 30 and 60 years old are more vulnerable than the young people but much less than the older group. Secondly, the membership function amongst 30 and 60 has been chosen 1-Dodecanol-d25 Cancer linear. This fuzzy membership function just isn’t precise only towards the islands of Guadeloupe but can be generalized anywhere on the planet and it depends upon the observations produced.Biology 2021, 10,six of0ageFigure 4. Fuzzy membership function of Hospitalization compartment as outlined by age (in years).Naturally, the second threat issue, obesity, includes a membership function similar towards the age, but we created a distinction involving women and males [28]. Obesity danger can cause the critical type of COVID-19, even for young persons [135]. The medical data [28] for Guadeloupe archipelago provided facts around the distribution of obesity by age and sex. We model this danger of vital kind linked to obesity (top to hospitalization) as a membership function which considers also the age for males and for females. The proposed fuzzyfication is presented in Figure five.ladies men0ageFigure 5. Fuzzy membership function of Hospitalization compartment with regards to obesity for males and females.In accordance with the health-related information, the proportion of obese women is about double that of men amongst adults, which implies a higher threat. The proportion of obese young persons is low for each sexes. Regarding the elderly, majority of men and women are obese, irrespective of gender. This aspect increases the danger and explains the shape in the membership functions described within the figure above. From these two membership functions of guys and women for obesity, we deemed a brand new observation obtained by aggregating the values of these two functions. As outlined by our data connected for the ratio amongst males and females in hospital as a consequence of COVID19 [27,30,31], we defined some weights that ponder these two membership functions. So as to respect the ratio of hospitalizations because of COVID-19 in Guadeloupe [27], we make use of the following weighted average: 0.6 f men + 0.4 f females (three)Biology 2021, 10,7 ofwhere f men may be the fuzzy membership function for obesity of guys and f ladies is the fuzzy membership function for obesity of ladies. We as a result have only one value for the danger of hospitalization in relation to obesity. 3.5. Fusion of Membership Functions To estimate the hospitalization price, we’ve got merged the two fuzzy functions corresponding respectively for the threat connected with age as well as the threat related with obesity. The merger is carried out with unique varieties of aggregation operators: the arithmetic imply the triple operator [32] the arithmetic imply is usually a averaging operator: these operators present 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 both positively reinforced and negatively reinforced. They favor extremes and accentuate differentiation.These two operators belong to two different categories [33]:In other words, the imply models a moderation and a balance of obesity and age elements, though if these two things have robust values, the tripl.
