Abstract
Semiconductor device manufacturing business has shifted from high-volume low-variety production to Agile Manufacturing. However, because the operation of production lines is conventional, production losses have made. Therefore, we study for optimization of a lot progress schedule according to the delay in lot progress and the condition of production equipment. We propose a model which optimizes lot processing balance. The model is one in some methods, and it makes a production loss minimize. In order to realize it, we suggest the multi-agent system which applied the concept of Grouping.
