考虑了保费收取为Poisson-Geometric过程,常利率环境条件下带干扰的两类相关理赔风险过程,把相关的两类理赔计数过程转换为两个独立的Poisson-Geometric过程和推广的Erlang(n)过程,并给出其折现罚金函数所满足的微积分方程。
A diffusion risk model which premium obeyed the Poisson-Geometric process with two dependent classes of risk processes under constant interest rate was considered, the correlated two claims in the counting process were transformed through model into independent Poisson-Geometric and generalized Erlang ( n ) processes. Integro-differential equations were obtained.
