Mathematical Economic Model of Minimizing Interest during Construction (Example - Nuclear Power Plant)
针对核电站等建设周期长、资本密集的项目，提出一个数理经济模型，用于在已知贷款条件下最小化建设期利息，帮助投资者在投资、预设计和设计阶段提高项目经济效率和竞争力。
Evaluating the investment attractiveness of large-scale, capital-intensive projects with long-term construction period such as the Nuclear Po wer Plant there is a problem of analysis of factors affect ing economic effect iveness and competitiveness. Generally capital-intensive projects are financed including the debt financing. Consequently during the construction stage one of the significant factors affect ing the economic effectiveness of the projects is the interest during construction (IDC) which increases the capital costs of the projects and could be one of the reasons for their inefficiency and lack of co mpetitiveness. So there is often a problem of min imizing IDC during the investment, predesign and design stages of the project. To solve this problem fo r a given (known or forecasted) loan conditions a mathematical economic model is offered in this article. Detailed algorith m of imp lementation of this model and an examp le of its application for the particular case are presented.
