The Data Centric Architecture of a Factory Digital Twin
Table 5-1 : Real-world FDT and their RTN statistics .
5.1 REALIZING VALUE WITH A DIGITAL TWIN STEP-BY-STEP
The FDT consists of two parts ( 1 ) a process model – the cycle times of steps , changeover times , material balance information , etc . structured as an RTN and ( 2 ) plant conditions which allow the process model to predict the future reality of the process from the present . The following is the best stepwise practice for developing an FDT . This bootstrap approach to developing an FDT builds confidence , rapidly provides value , and can help streamline business processes . For facility design / retrofit and facility fit applications Step 3 is not needed .
1 . The simplest process model should be developed in a manner that allows the digital twin to be used in practice to answer questions of interest . For example , this model can be for evaluating process improvement options , planning , etc . The output of this process model can be viewed on a Gantt Chart ( see Figure 5-1 ).
