Taking the ultra-precision joint bearing workshop as the research object, this paper develops a virtual simulation system integrating scheduling and layout optimization functions based on the Unity3D engine. By integrating the genetic algorithm, the standard NSGA-II algorithm and its improved algorithms, the system is capable of achieving dynamic scheduling and real-time layout optimization based on the actual operation data of the workshop. The system adopts a three-layer architecture of “modeling - algorithm - interaction”: the modeling layer constructs refined equipment models through SolidWorks and conducts lightweight processing in combination with 3ds Max; the algorithm layer integrates the SLP-GA hybrid layout optimization model and optimization algorithms such as NSGA-II to realize multi-objective optimization of workshop layout and production scheduling; the interaction layer develops functional modules using UGUI and C# scripts, supporting layout reconstruction, production process simulation and scene roaming. Through the verification of workshop examples, the system successfully realizes the visual verification of the scheduling scheme and the three-dimensional display of the layout optimization results, significantly improving the workshop logistics efficiency and production synergy. The research results provide a technical path for the intelligent upgrading of discrete manufacturing workshops and possess both theoretical value and practical significance.
