Abstract
In recent years, customer's needs are diversified or complicated, and it is necessary to a flexible manufacturing system in manufacturers. In order to design the system efficiently and economically using the KAIZEN activities, a virtual manufacturing system simulation is used. However, the simulation data cannot share and simulation cannot cooperate with external systems. In this research, expression of simulation data is proposed. The expression uses the XML language. The proposed one apply to the communication between a simulator and control demands.
