Abstract
Use for the paper transport simulation has begun with a purpose of improvement in design efficiency and performance such as a copying machine and a printer. And, the technology of the optimization design using optimization toool is being put to practical use with the improvement in the design quality and robust design. So, we tried the optimization design of the stacker form for the copying machine using the paper transport simulation and the optimization toool. Approach by quality engineering and approach by the mathematical optimization technique were compared.
