This proposal is for support of five separate but inter- related projects. The projects are: (1) Research on the iterative redesign model applied to parametric design of components: Modifying and extending an existing system to include the Taguchi philosophy of parametric design, and to include tolerance selection; (2) research on the iterative respecification model applied to parametric design of assemblies: Developing a first domain-independent version of the model, including tolerance selection; (3) research on features and designing with features for components: Extension of the current architecture and representation to deal with the more complexity, including tolerances, curved surfaces, feature combinations, user-defined features, and (possibly) functional intent; (4) research on a feature-based computer environment for conceptual design of mechanical assemblies: Extension of the current multiple level of abstraction representation to include multiple functional viewpoints; (5) research on extending the iterative redesign model to configuration and to conceptual design: Using features and concepts to assist evaluation and redesign of configuration and embodiments.

这一建议是为了支持五个独立但相互间的- 相关项目。 这些项目是：（1） 迭代再设计模型在参数化设计中应用 组件：修改和扩展现有系统， 参数化设计的田口哲学，并包括 公差选择;（2）迭代算法研究 应用于组件参数化设计的重新指定模型： 开发模型的第一个独立于域的版本， 包括公差选择;（3）特征研究， 使用零部件的特征进行设计：当前 架构和表示来处理更复杂的问题， 包括公差、曲面、特征组合 用户定义的功能，以及（可能的）功能意图;（4） 基于特征的概念设计环境研究 机械装配的设计：当前 多层抽象表示以包含多个 （5）迭代扩展的研究 再设计模型到配置和概念设计：使用 有助于评估和重新设计 配置和实施例。
