Abstract

Assembly instructions are process documents in detail describing the operation steps, materials, tools, fixtures, and assembly sequences in assembly procedures. Due to assembly instructions including numerous contents, and the content being easy for workers to understand, process designers need to spend lots of time thinking and authoring assembly instructions to ensure that workers can complete the assembly task according to the assembly instructions. Focusing on the difficulties of the variety of assembly instructions and the process factors implicit in the standard languages of assembly instructions, a method of assembly instruction generation for helicopter subassemblies is proposed. First, a data representation model of multi-source heterogeneous knowledge and information based on knowledge graphs is designed and established. Then, a hierarchical pruning VF3 algorithm is presented to reuse assembly instructions according to hybrid similarity. Finally, a process factor revision model based on RoBERTa-BiLSTM-CRF is proposed to generate revised assembly instructions. Helicopter subassemblies, which contain 11,240 assembly procedures, are used to evaluate the performance of the method for generating assembly instructions. The proposed method greatly reduces the time cost of assembly instruction authoring and promotes the intelligent development of assembly process design.

使用分层剪枝策略和大型语言模型生成直升机组件的装配指令
装配指导书是详细描述装配程序中的操作步骤、材料、工具、夹具和装配顺序的工艺文件。由于装配指导书包含的内容繁多,且内容易于工人理解,工艺设计人员需要花费大量时间思考和编写装配指导书,以确保工人能够按照装配指导书完成装配任务。针对装配指令种类繁多、标准装配指令语言隐含工艺因素等难点,提出了一种直升机分总成装配指令生成方法。首先,设计并建立了基于知识图谱的多源异构知识和信息的数据表示模型。然后,提出了一种分层剪枝 VF3 算法,根据混合相似性重用装配指令。最后,提出了一种基于 RoBERTa-BiLSTM-CRF 的过程因素修订模型,用于生成修订后的装配指令。直升机子装配体包含 11,240 个装配程序,用于评估生成装配指令方法的性能。所提出的方法大大降低了装配指令编写的时间成本,促进了装配工艺设计的智能化发展。

期刊介绍: The Journal of Industrial Information Integration focuses on the industry's transition towards industrial integration and informatization, covering not only hardware and software but also information integration. It serves as a platform for promoting advances in industrial information integration, addressing challenges, issues, and solutions in an interdisciplinary forum for researchers, practitioners, and policy makers. The Journal of Industrial Information Integration welcomes papers on foundational, technical, and practical aspects of industrial information integration, emphasizing the complex and cross-disciplinary topics that arise in industrial integration. Techniques from mathematical science, computer science, computer engineering, electrical and electronic engineering, manufacturing engineering, and engineering management are crucial in this context.
