针对铁路重载货车的不同设计指标进行方案优劣评价。在方案评价理论基础上，运用基于TOPSIS的支持向量机法，将TOPSIS的贴近度函数作为支持向量机评价方案的目标函数，对含有6个目标属性的某铁路重载货车的8个设计方案进行评价。研究结果表明：拥有容积与载重都相对较大，并且最高运行速度较高的方案为优选方案，而单一目标属性十分理想的方案并不是最优方案。根据方案评价结果对比，可以发现对铁路重载货车影响较大的因素为容积、载重及最高运行速度，而自重、轴重和制动距离这3个因素对方案的影响程度相对较小。

In this paper,schemes were evaluated by different design indexes of railway overloaded wagon.By means of scheme evaluation theory,support vector machine based on TOPSIS method was used.The closeness function was regarded as the objective function of support vector machine scheme evaluation.Eight design schemes of railway overloaded wagon were evaluated with six target attributes in each scheme.The evaluation re-sults show that a good scheme is seen as owning larger volume,weight and maximum operating speed.If only one target attribute is the best,the scheme may be not the optimum one.According to the evaluation results analysis, the schemes of railway overloaded wagon are affected seriously by volume,weight and the maximum operating speed.The impact of self-weight,axle load and braking distance on the schedule is relatively small.
