Harish Kumar Shahi completed a summer internship at Axalta Coating Systems where he worked on three projects: optimization of extruders, analysis of product wheel sequencing, and development of a planning software tool. He analyzed the constraints and throughput of eight extruders, identifying issues like cooling problems. This led to an average 10% increase in throughput. He also analyzed moving from bucket to product wheel sequencing, finding potential inventory and cost savings. Finally, he developed a software tool to optimize production planning and inventory levels.
