Abstract: Abstract A collection or group of distinct, well-defined things has a profound influence on our daily lives. But in reality, many circumstances appear to be very hazy, and in which things are only sometimes clearly defined. We discussed interval numbers, generalized triangular fuzzy number, and their Cut set in this study. The definitions of weighted arithmetic mean, weighted geometric mean, and weighted harmonic mean were also provided. Following that, the logistic equation for the population growth model was presented using an interval number and a fuzzy number. Finally, a mathematical demonstration using various fuzzy numbers is performed to illustrate its validity.
