摘要 讨论了一个带干扰更新风险模型的有限时间破产概率问题.在假设索赔额服从次指数分布,利率为常数的情况下,得到一个关于有限时间破产概率的近似表达式,并将此结论与利率为0时进行了对比. In this paper, the finite-time ruin probability for the jump-diffusion renewal process is considered. Under the assumptions that the claim-sizes are sub-exponentially distributed and that the interest force is constant, an asymptotic formula for the finite-time ruin probability is Obtained. Then the result is contrasted with the situation when the interest force is 0.
