Digital Twin Development for Serial Manipulators: Data Driven Optimized Planning and Sequencing of Tasks Studies in this area focus mostly on concepts, modeling approaches, frameworks and use cases of DT. 4 For example, various use cases of DT were presented, such as designs of products and production lines, 5 6 optimization of production processes 7 and shop floor DT. 8 Tesla, Siemens, General Electric, Dassault Systems and PTC have also implemented DT concepts in order to enhance their manufacturing capability. 9 Meanwhile, some researchers concentrate on I NTRODUCTION Digital Twin (DT) has been identified as one of the key technologies in the era of smart manufacturing to achieve several business benefits, such as improvements in productivity, efficiency and reduction of time to market for new products. Since the concept of a DT model was first introduced, research and development efforts in this topic were scarce due to the immaturity of enabling technologies. 1 Fortunately, recent breakthrough advancements in high performance computation engines, data acquisition systems, communication protocols, cloud computing, big data analytics and Artificial Intelligence (AI) algorithms have enabled the widespread implementation of DT and allowed for more studies on this topic. 2 3 1 Grieves, M.
