scope:

NEN-ISO 13379-2 gives procedures to implement data-driven monitoring and diagnostic methods to facilitate the work of analysis carried out by specialist staff typically located in a monitoring centre. Although some of the steps are embedded in existing tools, it is essential to be aware of the following steps for optimum use: - selection of the asset, the critical failures and the available process parameters; - data cleaning and resampling; - model development; - model initialization and tuning; - model performance evaluation; - diagnostics process. The implementation of these steps does not require a thorough knowledge of the statistical methods. It does require the competence first to build the training models and then to carry out monitoring and diagnostics processes.
