Abstract The paper discusses a perturbed Markov-modulated dual risk model with constant dividend barrier, in which, the gain arrivals, gains sizes and expenses are influenced by a Markov process. A system of integro-differential equations for the expected total discounted dividend payments until ruin is derived. Moreover, in the two-state model, explicit results are obtained when both claim amounts are exponentially distributed and mixed exponentially distributed. Finally, some numerical examples are given.

常数分红界下带扰动的马氏调制对偶风险模型
考虑常数分红界下带扰动的马尔可夫调制对偶风险模型, 其中保险公司收益到达过程、收益额的大小以及支出都受一马尔可夫过程的影响, 得到了破产前累积分红折现均值所满足的积分-微分方程及边界条件; 进一步得到了两状态下, 收益分布为指数分布和混合指数分布时累积分红折现均值的表达式, 最后给出了数值模拟实例.
