“…3by the Caputo fractional derivatives of orders q 1 , q 2 ∈ (0, 1], respectively, the resulting equations still have the problem in which the units of the left-hand side and the right-hand side of the resulting system mismatch, i.e., the units of the left-hand side are time q 1 and time q 2 while the units of the right-hand side of the system have the dimension time -1 . Hence, we must preserve units as described in [21,43] on both sides of each equation in the resulting system by adjusting some of the original parameters or multiplying some original parameters by a fractional time constant β. After taking care of the units for both sides of the equations, we obtain the delayed fractionalorder model of glucose-insulin interaction with incommensurate orders as follows:…”

“…Especially, we call the parameters α 1 and α 2 the fractional tissue glucose uptake rate and the fractional disappearance rate constant for insulin, respectively. As mentioned in the generalized MINMOD Millennium model [21], the terms β 1-q 1 and β 1-q 2 can be physiologically considered as the parameters describing the rheological behavior in enhancing the muscular and liver sensibility to the action of insulin. Roughly speaking, the new fractional-order model (29) is the generalization of the first-order system (3).…”

“…They typically convert the problem of model parameter estimation into an optimization problem, and then, formulate a suitable estimator by minimizing an objective function. These methods are stretched over but no limited to perturbation methods [60], weighted least squares approach [12,15,25], nonlinear regression [34], and Levenberg-Marquardt method [20,13,63,64]. We develop a bi-level FSEM-based parameter estimation method in order to construct fractional models, in a sense that the method obtains model coefficients in one level, and then searches for estimate of fractional indices in the next level.…”
