The old school performance system is based on daily reporting by the ship’s crew (noon data).
The intention of the reporting system is that the crew sends in average values of parameters over a certain period, normally 24 hours when the time at sea is of that length.
The values of the parameters included in the noon data are put into the model and the outcome is performance indexes for each day at sea.
A similar procedure with average values for each day is set up with auto logged parameters.
This causes a huge problem – scattered values in time and no actual evaluation of performance, so, it does not give a reasonable view of the ship’s performance
The auto-logged parameters and noon data in an old school performance system is stored in the form of excel files. Managing this kind of data format will become inefficient – especially if complex analytical algorithms have to be used for more advanced KPIs.
So, old school performance systems offer statistical performance management and not big data performance management like seametrico.
