A job-shop scheduling optimisation model to reduce work-in-process inventory and machine setup time: a case study in a plastic packaging manufacturing

Key Points

• The aim is to develop an optimisation model for job-shop scheduling to minimize work-in-process inventory and machine setup time.
• Developed a job-shop scheduling optimisation model focusing on inventory reduction and efficiency.
• Applied the model in a plastic packaging manufacturing setting to assess real-world effectiveness.
• Utilized simulation and analysis techniques to evaluate performance metrics.
• Successfully reduced work-in-process inventory by 25% after implementing the optimisation model.
• Decreased machine setup time by 15%, enhancing overall production efficiency.
• Improved resource allocation and workflow, leading to smoother operations.
