DISCOVERING THE POSSIBILITIES

Company: Kimball/Harpers – Office Furniture Manufacturer
Product Used: Custom System Package
Objectives: Develop a computer simulation model of a new Automated Electrostatic Paint Line System to identify cost effective methods to improve throughput capability to determine if a rate of 90 carriers per hour could be achieved.

Results: Before modeling for improvements, the current rate for carriers per hour was 46. Color change rates were in excess of 700 per 8-hour day. Rework was planned at approximately 30 percent. After building the model to establish the “baseline” process, a scheduling methodology was created and tested for a prime shift period. The results produced a minimum of 54 carriers/hr. with a maximum of 103 carriers/hr. and an average of 78 carriers per hour. There were 445 color changes and rework reduced to approximately 18 percent.
