Ranking calculation example
Step 1: Calculate KPI value
| PI003 | Actual unavailability | = 23 | |
| PI062 | Planned unavailability | = 18 | |
 |  |  |  |
Step 2: Calculate percentile rank by comparing KPI value against other ships with the same criteria. We assume that another 99 (100 in total) participate in the ranking with the same criteria and our ship has position 33 and you are the only ship in that rank.
Step 3: Calculate the percentile rank by capturing the count of all participant below your rank (cl). The frequency of ships in your same rank (fi). The total number of ships in the ranking segment (N).
Interpretation: Based on the above example, we could say that, when it comes to KPI032 Ship availability, this ship belongs in the 67.50th percentile of the ships that are being compared with based on its ranking criteria in the respective quarter.
