The approximate stock of capital for the system is calculated using Euler鈥檚 scheme in time discretization. Based on Barkholder-Davis-Gundys inequality and Gronwalls lemma, the error between the approximate stock of capital and the actual stock of capital is estimated by using mean squares. Theoretical analysis of the convergence of the approximate stock of capital is conducted.
