数字保存项目的投资存在着众多可以延迟的因素,不同时机投资获取的效益可能很不一样,因此寻求最佳投资时机是项目的一个重要决策。在假设投资和预期收益都遵从几何布朗运动模型的前提下,本文建立了数字保存项目投资机会价值模型,分析了投资机会收益率,探讨了影响投资机会选择的重要参数,并结合具体实例计算了投资机会价值和最佳投资规则,得出了投资时机选择对数字保存项目价值具有重大影响的结论。
There are many delays in the investment of digital preservation project. The benefits of investment at different times may be very different. Therefore, finding the best investment opportunity is an important decision of the project. On the premise of assuming that the investment and the expected return all conform to the geometric Brownian motion model, this paper establishes the value model of the investment opportunity of digital preservation project, analyzes the return rate of investment opportunity, discusses the important parameters that affect the choice of investment opportunity, and calculates The value of investment opportunity and the best investment rule, concludes that investment timing has a significant impact on the value of the digital preservation project.
