摘要
当保险精算利率与实际利率相等时,整个保险期间收支是平衡的,基金收益应为0;文章通过对利息力累积函数采用wiener过程建模,给出责任准备金的优化投资模型,使得保险基金在原本无收益的情况下,通过优化分段投资产生最大的期望收益并分析投资的稳定性,最后用实例模拟,取得了较好的效果。
Earnings of reserve funds should be zero When the actuarial rate of interest is equal to the real rate of interest. In this paper, the optimal investment model of reserve deposits under random rates of interest is modeled by the Wiener process. The model can make reserve funds which might have no economic profits bring maximum eXpected profits by the optimal reserve deposits. A simulation example is presented and a satisfactory result is obtained.
