Nowadays, substantial improvements in sustainable micro-manufacturing are explicitly addressed based on the triple bottom line (TBL) concept. However, strong criticisms are leveled for the applications of TBL as immense complexities of inner relationships of items and dimensional relationships within TBL, which they cause an inefficacy of accessing critical information in introducing the TBL concept to sustainable micro-manufacturing. In this study, social network analysis (SNA) is used for developing a TBL network of sustainable micro-manufacturing to find out precise meanings of individual items of various dimensions of TBL and the relationships between them. The main metrics of the dominant items of TBL such as in-degree, out-degree, betweenness centrality and closeness centrality are detailly discussed with 16 nodes for three dimensions in the TBL networks. The related findings are further analyzed to reveal the current situation, technical gaps and chances for the sustainable development of the micro-manufacturing sector. This study aims to reveal the relationship between the items of TBL of micro-manufacturing, and delivers the significant roles of the items of TBL according to the findings of metrics and visual analyses for sustainable micro-manufacturing, supporting micro-manufacturing sectors to implement effective sustainable strategies for production activities.

如今，基于三重底线 (TBL) 概念明确解决了可持续微型制造的重大改进。然而，TBL 的应用受到强烈批评，因为 TBL 内项目的内部关系和维度关系极其复杂，导致在将 TBL 概念引入可持续微制造时无法访问关键信息。在本研究中，社会网络分析（SNA）被用于开发可持续微型制造的 TBL 网络，以找出 TBL 各个维度的单个项目的精确含义以及它们之间的关系。TBL主导项的主要指标，如入度、出度、TBL 网络中三个维度的 16 个节点详细讨论了介数中心性和紧密中心性。进一步分析相关发现以揭示微型制造行业可持续发展的现状、技术差距和机会。本研究旨在揭示微型制造 TBL 项目之间的关系，并根据可持续微型制造的度量和可视化分析结果，传达 TBL 项目的重要作用，支持微型制造部门有效实施生产活动的可持续战略。
