基于灰色关联理论的自行火炮系统性能评估

System Capability Evaluation of Self-Propelled Gun Based on Gray Correlation Theory

结合自行火炮系统性能评估的特点,建立性能评估指标体系。应用层次分析法确定指标权重系数,建立基于灰色关联理论的评估模型,包括:确定方案集合以构造评估矩阵、数据的无量纲标准化处理、计算关联系数及关联度、综合评判分析。实例评估表明该法可行,能实现对自行火炮系统性能的评估分析,具有较高使用价值。

According to the characteristic of system capability evaluation of self-propelled gun, the index system of capability evaluation is established. The analytic hierarchy progress （AHP） is used to determine the weight-coefficients of index and establish the capability evaluation models based on gray correlation theory. The process includes setting up the scheme sets to construct the evaluation matrix, standardizing the data, calculating the gray correlation coefficients and the gray correlation degree, comprehensive estimate analysis. Furthermore, this model is confirmed by an example and the analytic results show that the model is feasible, which could actualize the capability evaluation of the self-propelled gun, and has high practice value.
