面向成本的设计中的多域特征映射研究

DFC(Design For Cost)是 DFX方法的一个分支 ,本文运用多域特征映射理论提出 DFC中特征域有 :4个设计域 (概念设计域、初步总体设计域、总体设计域和施工设计域 )和 5个成本域 (制造成本域、装配成本域、销售成本域、维修成本域、使用成本域、报废回收成本域 ) ,并在 DFC中建立了以设计域为核心的多域特征映射关系 ,通过综合应用神经网络、仿真和成组技术等方法 ,初步实现了设计参数与成本参数之间的映射 ,为 DFC中全生命周期成本(L CC- L ife Cycle Cost)的估算打下了基础

Research on Multiple Domain Feature Mapping in Design For Cost(DFC)

Using multiple domain feature mapping theory, we decomposed the DFC's feature domain. It includes four design feature domains (concept design domain, preliminary design domain,general design domain, and construction design domain) and five cost feature domains (manufacturing cost domain, assembly cost domain, sales cost domain, maintenance cost domain, use cost domain, reclaim and reject cost domain). Then we established multiple domain feature mapping relations among which design domain was the core in DFC. Using artificial neural network (ANN), simulation and group technology (GT), we preliminarily realized the mapping from design parameters to cost parameters.
