Theoretical and computational aspects of the considered model are discussed. We prove that the model has at least one solution and a unique solution using the Leray-Schauder and Banach contraction theorems. Using functional analysis, we investigate several types of Ulam-Hyres model stability. We use the predictor-corrector (P-C) method to construct a broad numerical scheme for the model's solution. The proposed numerical method's stability is demonstrated. Finally, we depict the numerical findings geometrically to demonstrate the model's dynamics.eninfo:eu-repo/semantics/openAccessethanol modelUlam-Hyres-Rassias stablegeneralized Caputo derivativeArticle919Q1WOS:000726251500001Q12-s2.0-8511604698210.3390/math9192370
