标题： Withdrawal Success Optimization

摘要： 对于$n$资产和离散时间再平衡，通过逐步可测的投资组合权重函数最大化完成给定投资和提款计划的概率。 应用考虑两种资产，即标准普尔综合指数和通胀保护债券。 对于涉及任意初始投资并随后在剩余时间段内等额年度提款的年度再平衡计划，计算最大概率和最优投资组合权重函数。 应用还考虑以美元成本平均（等额年度投资）开始的年度再平衡计划，然后转为等额年度提款。 结果表明，当使用最优投资组合权重而不是固定的投资组合权重（如将 90% 投资于标准普尔综合指数和 10% 投资于通胀保护债券的标准做法）时，完成给定计划的概率有明显提高。 显示英文摘要

摘要： For $n$ assets and discrete-time rebalancing, the probability to complete a given schedule of investments and withdrawals is maximized over progressively measurable portfolio weight functions. Applications consider two assets, namely the S&P Composite Index and an inflation-protected bond. The maximum probability and optimal portfolio weight functions are computed for annually rebalanced schedules involving an arbitrary initial investment and then equal annual withdrawals over the remainder of the time period. Applications also consider annually rebalanced schedules that start with dollar cost averaging (equal annual investments) and then shift to equal annual withdrawals. Results indicate noticeable improvements in the probability to complete a given schedule when optimal portfolio weights are used instead of constant portfolio weights like the standard of keeping 90% in the S&P Composite Index and 10% in inflation-protected bonds.
