根据公理化设计中物理集成的概念，产品的设计参数应集成到单个或几个物理部件中，以减少信息含量，同时仍满足功能需求的独立性。然而，文献中没有提出具体方法来确定给定设计中物理集成的最佳程度。这对于当前增材制造等技术的进步尤为重要。由于新的制造技术允许以新的方式集成物理元素，因此考虑到每个设计的特定约束和冲突，需要新的方法来帮助设计人员优化物理集成。本研究提出了一种使用图分区的算法，允许设计人员优化将功能需求集成到目标数量的零件中，目标是最大限度地减少同一零件中不兼容功能需求的共同分配。通过两个数值示例和设计铅笔的实际示例证明了该算法的操作和可行性。
According to the concept of physical integration as understood in axiomatic design, design parameters of a product should be integrated into a single physical part or a few parts with the aim of reducing the information content, while still satisfying the independence of functional requirement. However, no specific method is suggested in the literature for determining the optimal degree of physical integration in a given design. This is particularly important with the current advancement in technologies such as additive manufacturing. As new manufacturing technologies allow physical elements to be integrated in new ways, new methods are needed to help designers optimize physical integration given the specific constraints and conflicts of each design. This study proposes an algorithm that uses graph partitioning to allow a designer to optimize the integration of functional requirements into a target number of parts, with the goal of minimizing the co-allocation of incompatible functional requirements in the same part. The operation and viability of the algorithm are demonstrated via two numerical examples and a practical example of designing a pencil.
