| 摘 要： | 面向成本的设计(Design For Cost,DFC)是从设计的角度降低全生命周期成本(Life Cycle Cost,LCC)的设计方法。从DFC的角度,通过分析得到家用轿车的设计特征主要有外形尺寸、发动机功率、排量等参数,采用基于特征的神经网络集成方法,通过实例计算表明在概念设计阶段就可以估算其LCC,为降低其LCC奠定了重要基础。在计算BP神经网络权值时分别采用了Levenberg-Marquardt,LM法和遗传算法(Genetic algorithm,GA),对两种方法的计算结果进行了神经网络集成,集成后的结果更好。最后采用类似方法,对家用轿车的部分性能指标(100 km耗油量和车身质量)进行了预测。 |

| Abstract: | The design for cost(DFC) is a designing method for lowering the whole life cycle cost(LCC) from a design point of view.From the angle of design and through analysis,the designing characteristics that mainly contain parameters of outline dimensions,power of engine and delivery capacity etc.of family car were obtained.By adopting the characteristics based neural network integration method it has been indicated by means of a living example that its life cycle cost(LCC) could then be estimated during the phase ... |
