Figure 15.9 Diesel Ship Engines Report
Looking at the Event Plot, you can see that repairs for the Grampus4 engine have been relatively consistent,
but initially more frequent. Repairs for the Halfbeak4 engine have been more sporadic, and there appears to
be a spike in repairs somewhere around the 19,000 hour mark. This spike is even more obvious in the MCF
Plot.
Continue your analysis by fitting a parametric model to help predict future performance.
5. Select Fit Model from the red triangle menu next to Recurrence Analysis.
6. In the Recurrence Model Specification, select the Loglinear Nonhomogeneous Poisson Process.
7. Add the System ID column as both a Scale Effect and a Shape Effect.
8. Click Run Model.
