基于主成分分析的自行火炮作战效能评价

基于主成分分析的自行火炮作战效能评价，根据火力突击能力、机动能力和防护能力的具体效能指标，通过SPSS软件，建立主要综合性指标与自行火炮作战效能的关系，量化作战效能，步骤包括：对原始数据进行标准化处理，求标准化数据的相关矩阵，计算相关矩阵的特征值，确定主成分个数，最后计算缩减后的综合性指标。该方法客观上可为作战效能评价提供帮助。

Combat Effectiveness Evaluation of Self-Propelled Artillery Based on Principal Component Analysis

The paper evaluates combat effectiveness of self-propelled artillery based on principal component analysis. According to effectiveness index such as fire attack capability, maneuvering capability and protection capability, we established the relationship between main comprehensive index and self-propelled artillery＇s combat effectiveness, and qualified the combat effectiveness through SPSS software. The evaluation includes： standardized processing of original data, obtaining correlation matrix of standardized data, calculating eigenvalues of correlation matrix, determining the number of principal components and calculating the reduced comprehensive index. The method can provide help for combat effectiveness evaluation.
