摘　　要：提出了一种基于回归模型的卫星地面系统价格测算方法,以常用的服务器为例,经过数据收集及预处理形成样本集,作为估算建模的数据基础;筛选合适的配置参数,然后分析并选择一定的数据进行统计回归分析和训练,建立费用估算模型,对模型进行了验证和评估。将此方法应用至其他典型设备,拟合结果与实际价格基本一致,估算误差小于8%。该方法低成本、高效率、高可靠,可用于对卫星地面系统进行价格测算并定量明确费用驱动因子,为卫星地面系统论证阶段的经济分析提供有效支撑。A price calculation method for satellite ground system based on regression model was proposed,taking the commonly used server as an example,firstly,the sample set is formed through data collection and preprocessing,which is used as the data basis for estimation modeling.Appropriate configuration parameters are selected,and then a certain data relationship is analyzed and selected,and a cost estimation model is established through statistical regression analysis and training.Secondly,the model is validated and evaluated through analysis.Applying this method to other typical equipment,the fitting results are basically consistent with the actual price,and the estimation error is less than 8%.Research has shown that this method can calculate the price of satellite ground systems at low cost,high efficiency,high reliability,and universality,and quantify the cost driving factors,providing effective support for the economic analysis work in the demonstration phase.
