Abstract English We study the simulation of stochastic processes defined as stochastic integrals with respect to type G Levy processes for the case where it is not possible to simulate the type G process exactly. The type G Levy process as well as the stochastic integral can on compact intervals be represented as an infinite series. In a practical simulation we must truncate this representation. We examine the approximation of the remaining terms with a simpler process to get an approximation of the stochastic integral. We also show that a stochastic time change representation can be used to obtain an approximation of stochastic integrals with respect to type G Levy processes provided that the integrator and the integrand are independent.
