Concurrent design aims at reducing product development lead time and improving product overall quality by incorporating considerations in down-stream product development life-cycle aspects, such as manufacturing, into the early design stage. Over the past years, our research program has focused on development of new methodologies and software tools for supporting concurrent design, as well as their industrial applications. The research has led to considerable scientific contributions and noteworthy economical benefits. The proposed research program will extend the previously developed concurrent design methods to the optimal concurrent design of complex mechanical products and systems where multiple techniques are required in modeling, simulation and optimization of the mechanical products and systems. The long-term objective of this research is to develop the methodologies for the future CAD systems to support the optimal concurrent design functions. The proposed research will focus on the following aspects. (1) Introduction of a hybrid modeling scheme to integrate different types of product descriptions in different product life-cycle aspects. (2) Development of a hybrid simulation method to integrate various tools used for evaluations in different product life-cycle aspects into the same environment. (3) Development of a hybrid optimization method to identify the optimal design considering various evaluations from different product life-cycle perspectives in an effective and efficient manner. (4) Application of the developed concurrent design approach to the design of fuel cell systems. The research will introduce a new approach and many new computing methods/tools for carrying out concurrent design through modeling, simulation and optimization of complex mechanical products and systems. The new methods can be used for improving competitiveness of products in the market places. The proposed approach has the potential to form the key components in the future CAD systems that support the optimal concurrent design functions.

并行设计的目的是通过在早期设计阶段将下游产品开发生命周期方面的考虑因素（例如制造）纳入产品开发周期，从而缩短产品开发周期并提高产品的整体质量。在过去的几年里，我们的研究计划一直专注于开发新的方法和软件工具，以支持并行设计，以及它们的工业应用。这项研究已经产生了相当大的科学贡献和显著的经济效益。 建议的研究计划将以前开发的并行设计方法扩展到复杂的机械产品和系统的优化并行设计，其中需要多种技术在建模，仿真和优化的机械产品和系统。本研究的长期目标是为未来的CAD系统开发支持最佳并行设计功能的方法。 建议的研究将集中在以下几个方面。(1)介绍了一种混合建模方案，以集成不同类型的产品描述在不同的产品生命周期方面。(2)开发一种混合模拟方法，将用于不同产品生命周期方面评估的各种工具集成到同一环境中。(3)开发一种混合优化方法，以有效和高效的方式从不同的产品生命周期角度考虑各种评估，确定最佳设计。(4)并行设计方法在燃料电池系统设计中的应用。 通过对复杂机械产品和系统的建模、仿真和优化，为实现并行设计提供了一种新的途径和多种新的计算方法/工具。新方法可用于提高产品在市场上的竞争力。所提出的方法有可能形成在未来的CAD系统，支持最佳的并行设计功能的关键组件。
