摘要
本文研究了保费过程和索赔过程均为复合Poisson-Geometric过程的具有投资收益的双险种双复合Poisson-Geometric风险模型,利用概率论中的期望理论和切比雪夫不等式,得出此模型的调节系数不存在。在将干扰因素考虑进来后,得到了调节系数和破产概率的表达式。
A double compound Poisson-Geometric risk model with investment returns has been studied,in which the premium process and claim process are both Poisson-Geometric process.Using the expectation theory in probability theory and the Chebyshev inequality,it concludes that the adjustment coefficient of this model does not exist.After taking the interference factors into account,the expressions of the adjustment coefficient and the ruin probability are obtained.
