Abstract
V diplomski nalogi primerjamo zvezni in diskretni logistični model za opisovanje rasti z omejeno zgornjo mejo. Podrobneje obravnavamo pomanjkljivosti standardnega diskretnega modela, ki lahko pri določenih parametrih vodi v kaotično in nestabilno vedenje. Kot alternativo predstavimo izboljšano različico diskretnega modela, Verhulstov model, ki omogoča večjo stabilnost in ima eksplicitno rešitev, kar predstavlja njegovo pomembno prednost. S teoretično analizo in praktičnimi primeri na podlagi realnih podatkov o mobilnih naročninah, prebivalstvu Tokia in sintetičnih podatkih o bakterijski populaciji pokažemo, da se Verhulstov in zvezni model učinkoviteje prilagajata podatkom kot standardni diskretni model. Glavni prispevek diplomske naloge je prikaz uporabnosti Verhulstovega modela in izpostavitev prednosti njegovega analitičnega pristopa v realnih primerih.

Title:Comparing the discrete and continuous logistic models
Abstract:
In this thesis, we compare the continuous and discrete logistic models for describing growth with an upper limit. We address the limitations of the standard discrete model, which can exhibit chaotic and unstable behavior for certain parameter values. As an alternative, we introduce an improved version, the Verhulst discrete model, which provides greater stability and has an explicit solution, representing a significant advantage. Through theoretical analysis and practical examples using real-world data on mobile subscriptions, Tokyo's population, and synthetic data on bacterial populations, we demonstrate that the Verhulst and continuous models fit the data more effectively than the standard discrete model. The main contribution of this thesis is demonstrating the practical utility of the Verhulst model and highlighting the benefits of its analytical approach in real-world scenarios.

Keywords:logistic growth, discrete logistic model, continuous logistic model, Verhulst model, model comparison
