In this paper, we consider a bidimensional continuous-time renewal risk model with common shock claim-arrival processes. When both two lines of claim sizes are assumed to be strongly subexponential, a uniformly asymptotic formula for sum-ruin probability within finite time t is established. The obtained result extends the one in Cheng and Yu [Uniform asymptotics for the ruin probabilities in a bidimensional renewal risk model with strongly subexponential claims, Stochastics 91(5) (2019), pp. 643–656].

具有共同冲击相关性的二维风险模型的渐近和毁概率

在本文中，我们考虑具有常见冲击索赔-到达过程的二维连续时间更新风险模型。当假设两条索赔规模线都为强次指数时，则建立了有限时间t内和-毁概率的一致渐近公式。所获得的结果扩展了 Cheng 和 Yu 的 [ Uniform asymptotics for the Suder probabilities in a bidimensional recovery risk model with strong subexponential claim , Stochastics 91(5) (2019), pp. 643–656]。
