"Numerical solution of a new mathematical model for intravenous drug administration", Evolutionary Intelligence.1864-59091864-5917https://doi.org/10.1007/s12065-023-00840-4Perfilieva, Irina/0000-0003-1531-1111; Alijani, Zahra/0000-0002-1448-9068We develop and analyze a new mathematical model for intravenous drug administration and the associated diffusion process. We use interval analysis to obtain a system of weakly singular Volterra integral equations over ordinary functions. We then use the operational method based on Chebyshev polynomials for obtaining an approximate solution of the numerical form. We show that for a certain class of fuzzy number valued functions, their generalized Hukuhara derivatives can be reduced to the derivatives of ordinary real-valued functions. By using our approach, we are able to estimate numerical solutions very accurately.eninfo:eu-repo/semantics/openAccessDifferential EquationChebyshev PolynomialsFractional-Fuzzy Differential EquationsDynamic Of The BromsulphthaleinConcentration Of Drug In The Arterial TissueArticle17155957510.1007/s12065-023-00840-42-s2.0-85151503822WOS:000963148400001N/AQ2
