Abstract
Much emphasis has been given to minimize the time not only for design and manufacturing of products but also for development of manufacturing lines, in order to deliver products to market as soon as possible. However, planning, design and evaluation processes of manufacturing lines are very complicated, and individual engineers carry out the manufacturing lines' design based on their own experiences. It is now eagerly required to establish systematic methods and support tools, in order to support all the engineering processes for the planning, design, evaluation and redesign of the manufacturing lines. The objective of the research is to establish systematic methods and computerized support systems for manufacturing lines' design based on cluster analysis and sensitivity analysis.
