The process of product design specification is subjective in nature and this motivates the application of approaches and methods to make it explicit. Among the available approaches, the systematization of the development of a single product, modular products, family of products and products for mass customization stands out. Among the methods, the design structure matrix (DSM) is highlighted, as well as the use of networks to represent the variables and their interdependence relations. Representation is very important to increase the cognitive capacity of those involved in the design and to facilitate communication between specialists and non-specialists. The clarification of the knowledge and reasoning of the design increases the complexity of the specification, which needs to be managed. In this work, the method called design structure network (DSN) is proposed, allowing the visualization of the design variables as nodes of a network and the relations of interdependence as links and the specification reasoning can be represented as a path that connects the nodes in a network. For the management of network complexity, ten principles based on cognitive processes are implemented. The DSN method was applied in the geometric specification of surfboard, and the results obtained show the potential of graphical representation of the specification reasoning, as well as the ability to reduce the complexity of the network.

设计结构网络（DSN）：一种明确大规模定制的产品设计规范过程的方法

产品设计规范的过程本质上是主观的，这促使应用方法和方法使其明确。在可用的方法中，单一产品、模块化产品、系列产品和大规模定制产品的开发系统化最为突出。在这些方法中，突出了设计结构矩阵（DSM），以及使用网络来表示变量及其相互依赖关系。代表性对于提高参与设计人员的认知能力以及促进专家和非专家之间的交流非常重要。对设计知识和推理的澄清增加了规范的复杂性，需要对其进行管理。在这项工作中，提出了称为设计结构网络（DSN）的方法，允许将设计变量可视化为网络节点，将相互依赖关系可视化为链接，规范推理可以表示为连接网络中节点的路径。对于网络复杂性的管理，实施了基于认知过程的十项原则。将DSN方法应用于冲浪板的几何规范，所得结果显示了规范推理图形表示的潜力，以及降低网络复杂度的能力。对于网络复杂性的管理，实施了基于认知过程的十项原则。将DSN方法应用于冲浪板的几何规范，所得结果显示了规范推理图形表示的潜力，以及降低网络复杂度的能力。对于网络复杂性的管理，实施了基于认知过程的十项原则。将DSN方法应用于冲浪板的几何规范，所得结果显示了规范推理图形表示的潜力，以及降低网络复杂度的能力。
