Modeling and simulation for distributed computer control systems in a steel plant

The paper presents a modeling and simulation method to evaluate the performance of distributed computer control systems (DCCSs). Task response time, resource utilization, and network delay are considered as performance indices for time critical systems. The proposed DCCS model is composed of nodes, network, and environment model and their sub models are also described. The suggested method is applied to the DCCS of CAL (Continuous Annealing Line) in a steel plant and a new DCCS with an open network, in order to estimate the sustain performance.
