| Abstract: | In this paper,we consider a generalized risk model perturbed by diffusion involving two independent classes of insurance risks.By martingale approach,we assume that the two claim number processes are independent Poisson processes,an integro-differential equation for the ruin probability is obtained.The Lundberg inequality is derived.Finally,an example is presented. |
