摘要: 讨论了常利率带干扰的多险种多复合Poisson-Geometric风险模型,推导出生存概率满足的积分-微分方程。在没有保费收入的情况下,得到生存概率的Laplace变换的表达式,并给出数值计算的实例以说明所得结果。

Abstract: We discussed a multi-compound Poisson-Geometric diffusion risk model of multi-type -insurance with a constant interest rate,the integral-differential equation of the survival probability of this model was obtained. We obtained the explicit expression about Laplace transform of the survival probability when there were no premium incomes,finally ,a numerical example was given to illustrate the results.

Key words: multi-compound Poisson-Geometric diffusion risk model of multi-type-insurance with a constant interest rate, survival probability, integral-differential equation, Laplace transform
