摘要
考虑了一种带干扰双到达过程的风险模型,借助微分和It公式,获得了生存概率的积分微分方程.当索赔都服从指数分布时,得到了生存概率的微分方程.
In this paper, a risk model with perturbed double arrival process is considered. Integro-differential equations for survival probability of this risk model are obtained by differential calculus and Ito formula. When the claims are exponentially distributed, a differential equation for the survival probability is derived.
