Abstract: PROBLEM TO BE SOLVED: To facilitate the separation of a model and to enable the distributed simulation on complicated problems by simulating rolling process using a real time distributed model. SOLUTION: The simulation model of one rolling process is divided into real-time objects(RTO) of rolling and control. The former is divided into the RTO of a pay-off reel, tensin reel and each work roll and also the latter is divided into the RTO of a rolling speed controller and each automatic thickness controller. At the time of simulation, first, a communication channel is formed between the simulation RTO method and the RTO, the initial values of the simulation are allocated, parameters of the rolling process or the like is read in and the result value of simulation by the model is made to approach the target value. A means (object data store method) for recoding this parameter of rolling process when the parameter approaches the target value by a data space method of the RTO is repeated according to the period of simulation.
