Abstract Lean thinking has been proven effective in helping practitioners identify and eliminate wastes during engineering operations. However, systematic instructional mechanisms and training protocols based on individual trainee's performance are insufficient in existing training to define value-added activities for further productivity improvement in a training environment. This study aims to investigate how value stream mapping (VSM), as a lean tool, can be applied to help improve operation training performances through an immersive virtual reality (VR)-based personalized training program. A before–after experiment based on a virtual scaffolding erection scenario is established to simulate the training process. The training performance resulting from the VSM-based VR approach is compared with conventional VR training. Comparative results indicate that the waste time and errors reduce significantly. Compared with the conventional method, the overall productivity improvement of the erection process using VSM-based VR training is 12%. This demonstrates that integrating lean thinking into the operation training process can be a more effective approach for VR-based personalized operation training, provided that appropriate instructions are implemented.

基于价值流图的虚拟现实个性化操作培训采用精益思维

摘要 精益思想已被证明可有效帮助从业者识别和消除工程运营过程中的浪费。然而，在现有培训中，基于学员个人表现的系统教学机制和培训协议不足以定义增值活动，以在培训环境中进一步提高生产力。本研究旨在研究价值流图 (VSM) 作为一种精益工具，如何通过基于沉浸式虚拟现实 (VR) 的个性化培训计划来帮助提高操作培训绩效。建立了基于虚拟脚手架架设场景的前后实验来模拟训练过程。将基于 VSM 的 VR 方法产生的训练性能与传统的 VR 训练进行比较。比较结果表明浪费时间和错误显着减少。与传统方法相比，使用基于 VSM 的 VR 培训的勃起过程的整体生产力提高了 12%。这表明，将精益思想融入操作培训过程，可以成为基于 VR 的个性化操作培训更有效的方法，前提是实施适当的指导。
