英文摘要：
  In this paper, we use replica analysis to determine the investment strategy that can maximize the net present value for portfolios containing multiple development projects. Replica analysis was developed in statistical mechanical informatics and econophysics to evaluate disordered systems, and here we use it to formulate the maximization of the net present value as an optimization problem under budget and investment concentration constraints. Furthermore, we confirm that a common approach from operations research underestimates the true maximal net present value as the maximal expected net present value by comparing our results with the maximal expected net present value as derived in operations research. Moreover, it is shown that the conventional method for estimating the net present value does not consider variance in the cash flow.

中文摘要：
在本文中，我们使用复制分析来确定能够使包含多个开发项目的投资组合的净现值最大化的投资策略。复制分析是在统计机械信息学和经济物理学中发展起来的，用于评估无序系统，在这里，我们使用它将净现值最大化表述为预算和投资集中度约束下的优化问题。此外，通过将我们的结果与运筹学中得出的最大预期净现值进行比较，我们确认运筹学中的一种常见方法低估了真实最大净现值作为最大预期净现值。此外，研究表明，传统的净现值估计方法没有考虑现金流量的方差。
