This study aims to develop an innovative eco-design approach by integrating modules of LCA, CAD∖CAE and optimization to effectively include environmental considerations in product design. A life cycle modeling approach based on feature mapping scheme between product, operation and inventory has been employed to address the discrepancy in the principles of the utilized methodological approaches of LCA and CAD/CAE and enable data transformation between CAD/CAE and LCA models. In addition, by the feature-based life cycle modeling, product and process design parameters are then correlated to environmental impact proxy with explicit relationships, allowing designers to keep track of and optimize design changes that taking effect on both environmental and functional performance. Then, an integrated eco-design model consisted of a CAD-based geometric modeling module, a CAE-based functional performance analysis module, a feature-LCA-based eco-assessment module, and an eco-optimization module has been developed by Isight to realize automated procedures of low-environmental impact design. The proposed eco-design approach is expected to contribute to development of tools for efficient and practicable LCA during design and computer-aided eco-optimization with a complete view of the product life cycle.

这项研究旨在通过整合LCA，CAD∖CAE和优化的模块来开发一种创新的生态设计方法，以将环境方面的考虑因素有效地纳入产品设计中。已经采用了基于产品，运营和库存之间的特征映射方案的生命周期建模方法，以解决LCA和CAD / CAE所用方法论原理中的差异，并使CAD / CAE和LCA模型之间的数据转换成为可能。此外，通过基于特征的生命周期建模，可以将产品和过程设计参数与具有明确关系的环境影响代理相关联，从而使设计人员能够跟踪和优化对环境和功能性能均产生影响的设计变更。然后，Isight实现了低环境影响设计的自动化程序。预期所提出的生态设计方法将有助于设计和计算机辅助生态优化过程中高效，可行的LCA工具的开发，并全面了解产品的生命周期。
