This Small Business Innovation Research Phase II project proposes a framework to support product development, analysis, and decision making in multi-domain engineering environments through domain-unified product models. Ad hoc and even formal (standards-based) product data models, subject to the need for multiple views and attributes to support domain-specific application requirements, suffer from data redundancy and consistency problems. These problems are exacerbated by the implicit nature of information in geometric representation schemes and the difficulty and latency of its access. The intellectual merit of the work lies in the ability of the developed formalism to support the simultaneous generation and maintenance of multiple views of product model data, and the enforcement of consistency between them. A framework is proposed to manage the complexity of model synchronization and view-generation with the domain-unified modeling environment through the active management of constraints and goals for model population and transformation. The framework is to be validated within the context of an environment for the creation, management, and distribution of domain-unified models of packaged electronic components.The broader impact of this work accrues from the application of the domain-unified modeling methodology to packaged components for printed electronic assemblies (PCAs). The design of electronic products is realized through a combination of electronic design automation (EDA) software tools and computer-aided design (CAD) tools that support a wide variety of inter-related design and analysis disciplines spanning the electronic and mechanical domains (e.g. functional, layout, thermal, manufacturability). These tools are critically dependent on the availability of accurate computer-interpretable models of packaged electronic components. Due to the absence of accepted modeling standards, a lack of effective tools for the creation, maintenance, and distribution of component data, and a lack of interoperability across EDA and CAD tools. The proposed domain-unified modeling tools and data services will enable OEMs to more efficiently mange and distribute component information within their enterprises, OEMs and designers to leverage collective efforts in component modeling, and provide efficient mechanisms for the communication of data between component suppliers and OEMs.

这个小企业创新研究第二阶段项目提出了一个框架，通过领域统一的产品模型，支持多领域工程环境中的产品开发、分析和决策制定。特别的甚至是正式的（基于标准的）产品数据模型，由于需要多个视图和属性来支持特定于领域的应用程序需求，会受到数据冗余和一致性问题的困扰。几何表示方案中信息的隐式性质及其访问的困难和延迟加剧了这些问题。这项工作的智力价值在于开发的形式体系支持同时生成和维护产品模型数据的多个视图的能力，以及它们之间一致性的强制执行。提出了一个框架，通过对模型填充和转换的约束和目标的主动管理，来管理域统一建模环境下模型同步和视图生成的复杂性。该框架将在封装电子元件的领域统一模型的创建、管理和分发环境的上下文中进行验证。这项工作的广泛影响来自于将领域统一建模方法应用于印刷电子组件（PCAs）的封装组件。电子产品的设计是通过电子设计自动化（EDA）软件工具和计算机辅助设计（CAD）工具的组合来实现的，这些工具支持跨越电子和机械领域（例如功能，布局，热，可制造性）的各种相互关联的设计和分析学科。这些工具严重依赖于封装电子元件的精确计算机可解释模型的可用性。由于缺乏公认的建模标准，缺乏用于创建、维护和分发组件数据的有效工具，以及缺乏EDA和CAD工具之间的互操作性。提出的领域统一建模工具和数据服务将使oem能够更有效地管理和分发其企业内的组件信息，oem和设计人员可以利用组件建模中的集体努力，并为组件供应商和oem之间的数据通信提供有效的机制。
