近年来,商业银行信用风险的防范与管理一直备受各国重视。对其进行正确、有效的风险评估,应采用MATLAB工具和VisualC++程序构建基于遗传神经网络的商业银行信用风险评估模型,即运用遗传算法对BP神经网络进行优化,使模型实现优势互补,来仿真实现可操作的信用风险评估系统。以某商业银行提供的样本数据进行的实证分析结果表明:运用遗传算法优化权值的BP神经网络比未优化的BP神经网络对于商业银行信用风险的评估会更准确快速。这为制定我国商业银行信用风险的评估研究提供了参考,具有一定的理论和现实意义。
近年來,商業銀行信用風險的防範與管理一直備受各國重視。對其進行正確、有效的風險評估,應採用MATLAB工具和VisualC++程序構建基于遺傳神經網絡的商業銀行信用風險評估模型,即運用遺傳算法對BP神經網絡進行優化,使模型實現優勢互補,來倣真實現可操作的信用風險評估繫統。以某商業銀行提供的樣本數據進行的實證分析結果錶明:運用遺傳算法優化權值的BP神經網絡比未優化的BP神經網絡對于商業銀行信用風險的評估會更準確快速。這為製定我國商業銀行信用風險的評估研究提供瞭參攷,具有一定的理論和現實意義。

In recent years, risk prevention and management of commercial banks have attracted the attention of various countries. Correct and effective risk assessment of commercial banks can be conducted by setting up a risk assessment model based on genetic neural net-works with the application of MATLAB instrument and Visual C++program, namely simulating the risk analysis system by optimizing BP neural networks with genetic algorithm that makes the models complement each other. The empirical analysis of sample data of a commer-cial bank proves that it is more accurate and speedy for commercial bank risk control to optimize the weight of BP neural networks by ge-netic algorithm than the networks without the optimization. The result offers a reference to the study of risk assessment of commercial banks in China.
