本文考虑了一个保费收入过程为复合Poisson过程,且索赔时间间隔分布为广义Erlang(n)分布的风险模型,给出了其罚金折现期望函数所满足的瑕疵更新方程以及渐近表达式和精确表达式.
Considering a risk model where the premiums follow a compound Poisson process and the interclaim times follow a generalized Erlang(n) distribution.We derive a defective renewal equation for the expected discounted penalty function.The asymptotic and explicit results for the expected discounted penalty function are also discussed.
