工程车设计方案的综合评价与分析模型

Model for comprehensive evaluation and analysis of engineering vehicle design scheme

为了合理地评价工程车的设计方案 ,应用物元分析理论 ,根据工程车性能指标的具体特点 ,构造了适合工程车设计方案评价的关联函数。通过确定设计水平的经典域、节域、待评物元及关联度 ,建立了设计水平的综合评判数学模型。实例分析结果表明 ,综合评判数学模型较合理地反映了工程车设计方案所达到的设计水平 ,并定量地描述了工程车设计方案所存在的问题 ,为工程车方案设计的优化和各个设计参数的协调提供了数学依据。

To make a reasonable evaluation of the design scheme of engineering vehicles, the correlation function is constructed by using the matter element theory on the basis of the performance index and characteristics of the vehicle. And the mathematical model for comprehensive evaluation of the level of the design is established. A case study shows that the model reveals rationally the design level of the engineering vehicle scheme, and describes quantitatively the problems of the design scheme, therefore it can provide a mathematical basis for the optimum design of the engineering vehicle.
