Steelmaking, continuous casting and hot rolling are not only the key processes of steel production, but also the processes costing lots of energy. Pig iron is made into slabs by the process of steel making and continuous casting. The hot rolling process makes slabs into hot coil. A slab yard is built between the two parts as a buffer area to coordinate the production rhythm. In this work flow, if...
In order to complete the planning problem under the specific environment, an improved Artificial Glowworm Swarm Optimization (GSO) algorithm is proposed. In this algorithm, exchange and mutation is performed after each iterative. After each exchange and mutation the brightness of firefly, which related to fitness function value positively, is calculated and compared with brightness that has been got...
In this paper, a reconfigurable manufacturing execution system (RMES) based on events is researched. The system can acquire real-time information from control system. The basic infrastructure of the RMES is proposed. The key idea of the RMES is to define several meta-events according to the characteristics of production process. Many events are composed of several meta-events. All function modules...
