摘要 该文考虑了模糊厌恶下保险公司的最优投资和再保险问题,得到了保险市场和金融市场均存在模糊厌恶时,保险公司盈余的最小drawdown概率及其最优鲁棒投资和再保险策略的解析解.通过数值分析得出一些重要参数对值函数的影响. In this paper,we consider the optimal investment and reinsurance control problem for insurers with ambiguity,and we obtain the minimum drawdown probability,optimal robust investment-reinsurance strategies and the associated drift distortion.Moreover,some numerical examples are presented to show the impact of model parameters on the optimal results.
