基于设计模板的快速变型设计方法（Rapid Variant Design Approach Based on Design Template）
产品族 设计模板 快速变型设计 可变型单元
2009/8/11
传统的变型设计方法存在变型过程复杂，容易产生约束冲突的问题。针对零部件之间依赖关系复杂，设计过程需要通过交互和人工干预的形式才能完成配置与变型的问题，提出了在模板框架下的快速变型设计方法。利用模板的灵活性和信息载体功能，提出了可变型单元的概念，通过可变型单元之间建立相互关联实现对象之间的参数联动，在模板定义域范围内实现产品零部件的快速变型。以变速箱为实例，通过产品的结构变型实现产品的系列化，在同系...
针对复杂产品客户需求中类别数多且数据量大的分类问题，利用最小最大概率机的概率信息和样本间隔信息，提出采用启发式方法解决编码设计问题。在算法中将一个减少了迭代次数的分类器视为弱化了的分类器，同时保留分类器的间隔属性和几何特性，并利用高维映射将分类器输出映射到特征空间，在弱化阶段大量减少了整体的迭代次数而在合成阶段利用非线性映射来提升性能。通过对叉车产品客户需求的数值试验证明算法具有较好的分类效果，降...
