Research And Development Of A Dynamic Scheduling Model For Printing And Packaging Production

With the continuous upgrading of industry structure,breakthroughs in technology,and the expanding consumer market,the social demand for printing and packaging products is increasing.However,the level of intelligent production in printing and packaging in China is still relatively low.To address issues such as unreasonable resource allocation,inflexible production planning,and lack of real-time monitoring in printing and packaging production,this study developed a production scheduling system using information technology,production scheduling algorithms,and dynamic scheduling strategies.The system resolved issues such as high order delay rates,inflexible scheduling schemes,and lack of transparency,achieving a more orderly,visible,and controllable printing and packaging production process.Based on the characteristics and issues in printing and packaging production,the design requirements,business processes,and design principles of the printing and packaging production scheduling system were analyzed,and the overall system architecture was constructed.Using the B/S architecture,Vue framework,and Spring Cloud microservice framework,the system software architecture was designed to improve system performance and user experience.Additionally,functional modules and databases were designed to enhance the efficiency of internal business processes and data management.Real-time and complete production data was achieved through database collection technology and storage encryption mechanisms,improving data security and reliability.To address issues such as low equipment utilization and inflexible scheduling schemes in printing and packaging production scheduling,a mathematical model was established with three objectives: maximum completion time,total processing time of printing and packaging equipment,and total energy consumption of equipment.For static scheduling problems such as unreasonable resource allocation and low scheduling efficiency,a production static scheduling method based on the MOSGWO algorithm was proposed,which used a hybrid strategy for initializing the population,variable neighborhood search,and NSGA-II algorithm for optimization.Validation and analysis were conducted from three perspectives: case studies,performance,and examples.To address dynamic scheduling problems caused by equipment failures and emergency orders,a production dynamic scheduling model based on an event-driven mechanism was proposed,combining the MOSGWO algorithm with a dynamic scheduling strategy.The feasibility and effectiveness of the model were verified by simulating dynamic events under different circumstances.This study provides theoretical support for printing and packaging production scheduling problems and lays the foundation for engineering applications.Functionality,performance,and scheduling algorithm tests were conducted on the printing and packaging production scheduling system.The test results showed that the system can stably support 500 users simultaneously,with an error of less than 5%between the expected completion time and actual completion time of scheduling algorithms,and equipment utilization stabilized at around 85%.This system provides a reference for current research on printing and packaging production scheduling.
