ABSTRACT

Nowadays agile and practical methods for lean manufacturing and production process reengineering are in urgent need for Small and Medium Enterprises (SMEs). However, due to the limitations in obtaining accurate performance evaluations of the production line, traditional value stream mapping (VSM) methods are insufficient or unpractical in undertaking production process reengineering tasks. By integrating the internet of things (IoT) technology and Efficiency Validate Analysis (EVA) simulation framework, this paper proposed a digital twin-enabled VSM approach for SMEs. This easy to adopt and accurate method helps manufacturing SMEs in redesigning and reengineering production processes. This study contributes to research on digital twin modeling, by proposing a theoretical framework which combines IoT data-driven production process planning and simulation methods. The novelty of this study also exists in proposing a comprehensive and practical solution for production process reengineering, which integrating the cutting-edge technologies including digital twin and IoT. The feasibility and validity of the proposed approach is proved by applying to a musical instrument factory in China.

摘要

如今，中小型企业 (SME) 急需敏捷实用的精益制造和生产流程再造方法。然而，由于在获得生产线的准确性能评估方面存在局限性，传统的价值流图（VSM）方法在承担生产流程再造任务方面是不够的或不切实际的。通过集成物联网 (IoT) 技术和效率验证分析 (EVA) 模拟框架，本文提出了一种面向中小企业的数字孪生启用 VSM 方法。这种易于采用且准确的方法有助于制造业中小型企业重新设计和重新设计生产流程。本研究有助于数字孪生建模的研究，通过提出结合物联网数据驱动的生产过程规划和模拟方法的理论框架。本研究的新颖之处还在于提出了一种综合实用的生产流程再造解决方案，融合了数字孪生和物联网等前沿技术。以国内某乐器厂为例，证明了该方法的可行性和有效性。
