参数估算法能够将影响维修费用的各种客观因素综合考虑，通过建立回归模型，对反舰导弹维修费用进行科学地直接估算。偏最小二乘回归方法在处理样本容量小、自变量多、变量间存在严重多重共线性问题等方面具有得天独厚的优势。文章综合分析了影响反舰导弹维修费用的各种因素，建立了基于偏最小二乘法的费用估算模型，设计了精度评定方法。通过实例计算验证，该方法建立的模型拟合度好，变量累计解释能力强，估算误差在5％内。

Parameters estimating methods can make every objective factors be considered comprehensively that affect the maintenance cost, the maintenance cost of anti-ship missiles can be directly calculated scientifically by regression model. Partial least squares methods have incomparable advantages in aspects of small samples＂ handling, more independent variables and multi-share with linear characteristics of variables. Most kinds of factors that affected the maintenance cost of anti-ship missiles were comprehensively analyzed, and the model of partial least squares methods was built and the means of precision evaluating were designed. The case proved that the model build by these methods had high degree of fitting, strong ability of variables explaining, and the estimating error within 5%.
