Multi-relational real world manufacturing process data (FCUP, CMF)

The dataset comes from a real world manufacturing process of a Critical Manufacturing business partner. The manufacturing process is monitored via a IoT system. The dataset has been carefully anonymized due to privacy concerns, for more details on how this process was conducted see the accompanying thesis.<br>In the case of the process that generates this data eight different readings are taken each time a particular tool is used. Eventually once a tool begins underperforming, it is retired and therefore does not again again appear in the dataset. We believe that this dataset may be used to estimate and predict tool longevity, as it likely presents time dependent covariates as such be of use to the research of multilevel survival analysis or predictive maintenance models.<br><br><br>Name |Type |Description--------------------------|---------------------|---------OperationEndTime |Numerical |Difference in seconds from the first operation in the dataset.ToolId |Numerical Key |The tool used.
