In the textile industry, which has low energy efficiency, dyeing and finishing shop accounted for 42 percents of the total energy consumption. In addition, the dyeing and finishing shop has a low standardization level for process and setup, and is based on know-how of operator in the field according to incorrect instruction from the laboratory. To improve the energy efficiency of the dyeing and finishing shop, the process was standardized based on manufacturing data from the dyeing process. This study suggests a configuration and a utilization plan to operate digital twin to provide decision making supporting based on interoperability scenario with manufacturing data. The digital twin is a virtual factory model that reflects real-world components and interacts with the physical world and other applications. It also contains information and functional units, which are used to interact with big data from a dyeing and finishing shop with various algorithms. Thus, this study first defines the interoperability scenarios that should be used to provide a variety of decision making support information through the utilization of digital twin, and how they should be reflected the manufacturing elements and functional units of the physical world. This provides a fundamental knowledge of the process and systematical approach to improve energy efficiency.
