A Novel Multi-Agent-Based Collaborative Virtual Manufacturing Environment Integrated with Edge Computing Technique

This paper proposes a multi-agent-based collaborative virtual manufacturing environment (VME) to save energy consumption and improve efficiency in the manufacturing process. In order to achieve the high autonomy of the manufacturing system, a multi-agent system (MAS) is designed to build a collaborative VME. In this new VME environment, edge computing is embedded to strengthen the cyber resource utilization and system economy. Moreover, an efficient communication channel between networks is proposed. The subsequent cooperation and collaboration protocols among agents are designed to ensure flexible and process-oriented operations. Furthermore, the fuzzy resolution algorithm is employed to resolve the competition conflicts among function-similar MASs in the distributed manufacturing scenario. Lastly, a simulation and case study are performed to evaluate the performance of the proposed VME in Internet of Things (IoT)-based manufacturing. The analysis results have demonstrated the feasibility and effectiveness of the proposed VME system.

A Publishing Method of Lightweight Three-Dimensional Assembly Instruction for Complex Products

In order to accurately guide on-site workers to quickly accomplish the assembly job of complex products, and reduce the deployment cost of assembly instruction, we propose a publishing method of lightweight 3D assembly instruction for complex products. In this paper, the key frames of assembly motion and the 3D technical annotations in the lightweight model are mapped to the time-based assembly process. Then, the annotated lightweight model and assembly process information are integrated and published into a single 3D assembly instruction document. An assembly instruction publishing example of satellite antenna feed component shows that the lightweight 3D assembly instruction is well instructive and affordable because it provides the interactive simulation of assembly process and time-based display of assembly technical annotations without using expensive computer-aided design (CAD) systems, graphics workstations, or virtual reality equipments. This method gives a full play to the advantages of model-based definition technology and lightweight model, and fills the gap between the process planning and the instruction publishing in the 3D virtual manufacturing environment.
