摘要
政治风险是国际工程项目最常见的风险,在分析国际工程项目政治风险基础上,提出了一个基于BP神经算法的国际工程项目政治风险评价模型。该模型可以学习专家知识,具备自适应能力。实证研究表明,该模型能够较准确预测政治风险对国际工程项目成本的影响,验证了文中方法在复杂政治风险条件下的有效性。
Political risk is one of the common risks in international construction projects, the political risk is analyzed in this paper and an evaluation model of political risk in international construction projects is presented based on BP algorithm, The model is a self- study and self- adaptive one in risk evaluation. Through the simulation study with practice data, with this model the cost improvement of international construction projects can be predicted in political risks exactly, it is useful in evaluating the comprehensive political risk.
