9300253亨德森 对高质量、多样化产品的需求不断增长，要求设计工程师以更快、更便宜的速度提供新的、更好的设计。 这一目标的核心是需要在设计过程中评估拟议设计特征的可制造性。 虽然研究人员已经开始了评估设计的工作，但设计和制造过程之间的许多重要环节仍然没有开发。 这一跨学科的研究涉及以下目标：（1）基于制造考虑向设计者提供可理解的重新设计帮助的反馈系统，（2）将设计相关的产品模型转换成用于制造评估的适当的制造相关的、基于特征的模型的合理的、务实的方式，（3）将特征与工厂能力相匹配的局部工厂模型和基于关键知识的辅助，（4）用于预测所提出的产品特征和制造过程的统计过程性能的算法，以及（5）结合统计过程性能、时间和成本的制造评估方法。 本研究改善了并行工程环境，为设计人员提供快速、有效的帮助。 该系统评估产品的可制造性，并将可能导致成本和质量问题的原始设计变量的信息反馈给设计师。

9300253 Henderson The increasing demand for high-quality, diversified products is requiring the design engineer to deliver new and better designs faster and cheaper. Central to this goal is the need to evaluate the manufacturability of proposed design features during the design process. Although researchers have begun work in evaluation designs, many important links between the design and manufacturing process remain undeveloped. This interdisciplinary research addresses the following goals: (1) a feedback system that provides designers with understandable redesign help based on manufacturing considerations, (2) a legitimate, pragmatic way of converting a design-related product model into an appropriate manufacturing- related, feature-based model used for manufacturing evaluation, (3) a parochial factory model and key knowledge-based assistants to match features with factory capability, (4) algorithms for forecasting the statistical process performance for proposed product features and manufacturing processes, and (5) a manufacturing evaluation methodology that incorporates statistical process performance, time and cost. This research improves the concurrent engineering environment by providing fast, efficient help to the designer. The system evaluates a product for manufacturability and feed back information to the designer in terms of the original design variables that may cause problems in cost and quality.
