考虑两类索赔相关风险模型.两类索赔计数过程分别为独立的广义Poisson过程和广义Erlang(2)过程.得到了该风险模型的罚金折现期望函数满足的积分微分方程及该函数的Laplace变换的表达式,且当索赔额均服从指数分布时,给出了罚金折现期望函数及破产概率的明确表达式.
In this paper two-correlated claims model is considered. Claim occurrence of both classes relates to the generalized Poisson and generalized Erlang(2) processes. Integro-differential equations satisfied by the expected discounted penalty functions are derived. Laplace transforms of the expected discounted penalty functions are obtained. Explicit results of the expected discounted penalty functions and ruin probability are derived when the claims from both classes are exponentially distributed.
