Model build
The model build phase is the most critical step in the project, and getting it right is vital for the project's success. To be able to do that, all the steps prior to this step need to be executed to a very high standard, from defining the scope and getting everything documented in the FDS and the DDS to getting the correct P&IDs, datasheets, H&MBs, and steady state models, and some input from the operations team on how the process is engineered and operated. The latter will help the modelers better understand the process and will highlight what the operations team sees as potholes to avoid or explore in the model to show operation engineers and operators how to optimize their process.
The first thing the lead modeling engineer will need to decide with their team is whether the model is going to fit in one big model or whether it needs to be broken into smaller pieces.
All modeling packages will have issues around model-to-model communications, so keeping...
