It is suggested that model versions used for nobuild and build analysis are captured in terms of corresponding filenames and folder names. Typically, each version or revision is associated with a date or timestamp for efficient tracking. Versioning helps document changes to the model and helps control all changes applied to a model, allowing the identification and recovery of a previous version when needed. Model version controls are typically documented and include tracking of the changes and data inputs made in each model revision. See

Chapter 7, Section 7.5.5

of this manual for definitions of no-build and build.
