ABSTRACT Physical architecture is important for the design of complex products since it is a mediator between conceptual design and detail design. An efficient generation and evaluation method for physical architecture is imperative for successful design. Substantial research on architecture generation and evaluation has been conducted. However, various deficiencies exist, such as component combination explosion. In this study, an automated generation and evaluation method for feasible and ranked physical architectures is proposed. First, a unified knowledge model is established, and the components that can realise the specified function in the functional architecture are identified. Then, the corresponding components of each function are combined via a dynamic-programming-based method. In this combination process, the compatibility of components with one another is checked to avoid the component combination explosion issue, and the basic information of combination is collected. Finally, the relationship between the product criteria and the components’ properties is constructed, and the feasible physical architectures are evaluated hierarchically based on Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS). This automated method generates and ranks all feasible physical architectures efficiently and helps system designers make fast trade-offs. An automobile case study is presented to demonstrate the capability of this method.

用于复杂产品设计的自动化物理架构生成和多标准评估的集成方法

摘要 物理架构对于复杂产品的设计很重要,因为它是概念设计和详细设计之间的中介。物理架构的有效生成和评估方法是成功设计的必要条件。已经对架构生成和评估进行了大量研究。但是,存在各种不足,例如组件组合爆炸。在这项研究中,提出了一种可行的和排序的物理架构的自动生成和评估方法。首先,建立统一的知识模型,识别出功能架构中能够实现指定功能的组件。然后,通过基于动态规划的方法组合每个函数的相应组件。在这个组合过程中,检查组件之间的兼容性,避免组件组合爆炸问题,并收集组合的基本信息。最后,构建了产品标准与组件属性之间的关系,并基于与理想解决方案相似的订单偏好技术(TOPSIS)对可行的物理架构进行了分层评估。这种自动化方法可以有效地生成所有可行的物理架构并对其进行排序,并帮助系统设计人员进行快速权衡。提出了一个汽车案例研究来证明这种方法的能力。构建产品标准和组件属性之间的关系,并基于与理想解决方案相似的顺序偏好技术(TOPSIS)对可行的物理架构进行分层评估。这种自动化方法可以有效地生成所有可行的物理架构并对其进行排序,并帮助系统设计人员进行快速权衡。提出了一个汽车案例研究来证明这种方法的能力。构建产品标准和组件属性之间的关系,并基于与理想解决方案相似的顺序偏好技术(TOPSIS)对可行的物理架构进行分层评估。这种自动化方法可以有效地生成所有可行的物理架构并对其进行排序,并帮助系统设计人员进行快速权衡。提出了一个汽车案例研究来证明这种方法的能力。
