A simple mathematical model of human liver function is a linear system of differential equations
consisting of two unknown functions and their first order derivative.Since laboratory data and clinical
values are recorded by measurement and evaluation, they have the characteristic of uncertainty and
inaccuracy. This paper deals with the analysis and solving of the model with fuzzy data. At first, the
problem is investigated in fully fuzzy case from the point of view of generalized Hukuhara differentiability,
and sufficient conditions for the existence of a unique solution are found. Next, the simpler
forms of the problem are studied in two separate cases of the fuzziness of parameters, and in each
case, the solution formulas are obtained, in details. In the end, two numerical examples are solved to
describe and apply the results in practice.
