考虑常利率及通货膨胀下有扰动的双复合Poisson-Geometric过程的两险种风险模型,运用鞅方法得到破产概率满足的Lundberg不等式和一般公式,当保费和索赔服从指数分布和混合指数分布时,得到破产概率的精确表达式。
In this paper,we take the perturbed double-type insurance risk model with constant interest rate and inflation of double Poisson-Geometric process into consideration.By applying the martingale approach,the Lundberg inequality and the formula of ruin probability are obtained.When the premiums and claims follow exponential distribution and mixed exponential distribution,accurate expressions of ruin probability are derived.
