摘要: 该文考虑变保费率的扰动风险模型, 其中索赔的分布是重尾的. 对这个风险模型, 给出了索赔剩余过程的精细大偏差; 同时, 还得到了它的有限时间破产概率的Cramer-Lundberg型极限结果.

Abstract: In this paper, the authors consider a perturbed risk model with variable premium rate and heavy-tailed claims. The precise large deviation for the claim surplus process of this risk model is obtained. The Cramer-Lundberg type limiting results for the finite time ruin probability are also given.

Key words: Variable premium rate, Brownian Motion, Perturbed risk model, Precise large deviation, Ruin probability
