摘要
研究各期存款(包括购国库券)利率及银行取款政策后发现:每年奖金额均来自于存款的利息;若每笔本金到取款时能获得最大综合本利率,则奖金额就可获得最大值.据此,建立了基金使用模型,设计了一个有效的算法,并通过编程在计算机上实现了这个算法,成功地解决了三种情况下(①只存款不购国库券;②可存款也可购国库券;③第3年的奖金比其他年度多20%)最佳基金存储设计问题,并对每年奖金额不等、年数n任意等都有效.
By analysis, we found that every year＇s premium arose from profits of savings, so we could get maximum premium if the multiple rate of interest is maximum. Then we designed an optimized model on funds saving, which provided an effective algorithm and program and finally got every year＇s maximum amount of premium in three conditions.
