Abstract
The development of an effective decision-making system for change orders is necessary when considering a steel production management system, including efficient production progress monitoring and automatic data collection. This paper introduces the detailed decision-making processes and verification of the information required to make appropriate decisions to deal with change orders in steel fabrication projects. The study was performed based on a Japanese steel fabrication project, with components produced by a large-scale steel fabrication plant in Thailand. Firstly, the authors analyzed the detailed response process for order changes, and the information referenced in order to make those decisions. Secondly, we studied the monitoring methods of production progress in the factory. Finally, we introduce an implementation case, as a production management system for steel fabrication to support decision-making, this includes assignments remaining, such as the limitation of identification technology in harsh environments, delayed input information dependent on monitoring timing and input method.
