Development of a computer-aided modular design system based on product lifecycle scenarios

为了在不降低产品价值的情况下减少整个产品生命周期的环境负荷和资源消耗，生命周期设计是一种有希望的方法。产品生命周期的设计包括规划生命周期策略，从不同的角度评估它们，并优化整体图景。通过在生命周期设计的早期阶段描述生命周期场景，可以明确地规划产品生命周期策略，并设计产品以实现该场景。在本研究中，我们开发了一个生命周期设计的计算机辅助设计环境，称为“生命周期CAD”系统。系统将我们定义的生命周期模型与产品架构联系起来，并管理它们之间的一致性。案例研究表明，生命周期模型和产品模型之间的关系以一种集成的方式在计算机上成功地表示出来，以支持产品生命周期设计。

For reducing environmental loads and resource consumption over the entire product life cycle without decreasing the product's value, life cycle design is a promised approach. Design of a product lifecycle involves planning lifecycle strategies, evaluating them from various viewpoints and optimizing the overall picture. Product lifecycle strategies can be planned explicitly by describing lifecycle scenarios at an early stage of lifecycle design and the product should be designed to realize the scenario. In this study, we developed a computer-aided design environment for lifecycle design called "Life-Cycle CAD" system. The system links a lifecycle model we defined with product architecture and manages the consistency between them. Case studies clarified that the relationship between the lifecycle model and the product model is successfully represented on a computer in an integrated manner to support product lifecycle design.
