制造系统设计是一个复杂的工程领域，需要多学科的理论和实践支持。因此，制造系统设计课程中的概念和主题不容易被学生掌握。虚拟现实（VR）技术的进步提供了一个新的机会，可以在虚拟3D模型中实现来自工业现实实践的复杂工程理论。作者开发了一个独特的排队论虚拟现实教学模块，可用于制造系统设计课程。该模块使用Oculus Rift耳机、Oculus Touch和UNITY 3D软件包。这个VR教学模块的功效通过模拟疾病，系统可用性和用户体验工具来衡量。统计分析表明，虚拟现实教学模块是一个用户友好的和有效的工具，提供决策理论。大约91.7%的参与者经历了中度以下的模拟疾病，没有人退出研究; 91.67%的人对系统可用性的满意度高于平均水平。平均用户体验为3.625（满分6）。研究结果还表明，系统可用性对学生的知识获得有影响，但对学习动机没有影响，而用户体验对学生的知识获得和学习动机有影响。VR教学模块在知识获取和动机方面优于传统教学模块。总体而言，研究结果证实了VR技术在排队论教学中的有效性。
Manufacturing system design is a complex engineering field that requires cooperated and aggregated multiple-disciplinary theoretical and practical support. Thereby, the concepts and topics in manufacturing system design courses are not easy to grasp by students. Advances in virtual reality (VR) technology present a new opportunity that can provide the implementation of complex engineering theory from industrial real-life practice in a virtual 3D model. The authors developed a unique queuing theory VR teaching module that can be used in a manufacturing system design course. The module uses Oculus Rift headset, Oculus Touch, and UNITY 3D software package. The efficacy of this VR teaching module is measured through simulation sickness, system usability, and user experience tools. The statistical analysis shows that VR teaching module is a user-friendly and efficient tool for delivering queueing theory. Approximately 91.7% of the participants experienced below moderate level simulation sickness and none of them withdrew from the study; 91.67% had "above average" satisfaction in terms of system usability. The average user experience was found to be 3.625 out 6. The results also show that the system usability has impact on students' knowledge gain but not motivation, while user experience can affect student's knowledge gain and motivation. VR teaching module outperforms the traditional teaching module in terms of knowledge gain and motivation. Overall, the findings of the study confirm the efficacy of VR technology in teaching queuing theory.
