基于BP神经网络的项目评估模型研究

项目的申报、实施、验收都需要进行项目评估，项目评估是项目实施过程中的重要工作。项目评估复杂、专业，评估过程和结果具有很强的主观性。BP神经网络具有容错性强、信息分布处理能力高、自主学习、自适应、非线性映射等特点，适合推理规则不明确或推理规则非线性的环境，具有人脑思维的特征，BP神经网络在工程、管理、经济等领域得到广泛应用。在项目评估领域，现在基本上仍然以领域专家主观评价为主，这对评估结果的客观性、公正性必然会带来影响，评估过程信息化是项目评估改进的方向和趋势。基于评估的一般过程和BP神经网络的基本思想设计出项目评估的一般模型具有现实意义，应用BP神经网络建立项目评估模型的应用价值值得关注。

Study on Project Evaluation Model Based on BP Neural Network

Project evaluation is an important work in project implementation process,it can't be separated from project evaluation in declaration,implementation,and inspection of a project.Project evaluation is complex and professional,and it is highly subjective to the evaluation processes and results.The BP neural network has some characteristics such as strong fault-tolerant,high ability of distributing and conducting information,self-learning,adaptive,nonlinear mapping and so on.It is suit for the environment that...
