产品随着时间的推移而发展，以满足新的客户需求、技术和市场。产品的进化过程必然涉及产品结构的变化，这种变化可能以固有的进化属性为特征。虽然从不同的角度讨论了产品演化，但从分析的角度来看，尚未充分探讨产品结构演化的潜在特性。网络科学的各种经验和理论研究表明，代表不同类型复杂系统的真实网络不是随机结构的，而是具有一定的性质，而不管其起源如何。本研究着眼于现实网络的拓扑通用性，旨在通过对代智能手机模型的案例研究，揭示基于网络科学方法的产品结构的内在演化特性。首先，将每代产品的产品结构表示为产品结构网络。然后，通过网络测度和基元分析各网络的拓扑特征和模式。结果表明，产品结构网络可能遵循在其他真实网络中观察到的普遍性质；产品结构成长为一个无标度的网络，具有共同的构建模块。本研究的结果表明，识别的属性可以作为理解和制定产品演变的基础，以获得拓扑稳健性和模块化的设计效益。
Products evolve over time to satisfy new customer needs, technologies, and markets. The evolution process of products necessarily involves changes in a product structure that might be characterized by inherent evolving properties. Although product evolution has been discussed from various perspectives, the underlying properties of an evolving product structure have not been sufficiently explored from an analytical view. Various empirical and theoretical studies in network science show that real networks representing different types of complex systems are not randomly structured but are characterized by certain properties regardless of their origins. Focusing on the topological universality of real networks, this study aims to reveal the inherent evolving properties of a product structure based on a network science approach through a case study of generational smartphone models. First, the product structure of each generational product is represented as a product structure network. Then, topological characteristics and patterns in each network are analyzed by network measures and motifs. The results show that the product structure networks may follow the universal properties observed in other real networks; the product structure grows as a scale-free network with common building blocks. The findings from this study suggest that the identified properties can be used as a basis to understand and formulate product evolution to obtain design benefits from topological robustness and modularity.
