摘要
简要回顾了遗传规划的发展,对其基本原理进行了阐述,提出了基于遗传规划的飞机维修保障费用预测模型,并依据样本数据对所建模型的有效性进行了验证。实例表明,与线性回归方法和偏最小二乘回归方法相比,遗传规划在飞机维修保障费用预测中精度更高,具有较好的应用前景和推广价值。
After a review of development on genetic programming （GP）, its elementary theory is elaborated. A new forecast model employing GP is then advanced and is validated with the sample data. The calculation results show that GP model has higher accuracy in cost forecast for aircraft maintenance support compared with methods of linear regression and partial least-squares regression and is preferable in application.
