Overall equipment effectiveness
OEE multiplies three percentages together into one number that plant managers compare across lines.
- Availability, performance and quality are each a percentage from 0 to 100.
- The score is the three multiplied and brought back to a percentage, rounded half up.
- Anything outside 0 to 100 is clamped into range before the sum.
oeeScore(availability: int, performance: int, quality: int) → int
Java needs a compiler and Drill does not host one yet, so this page is the reference rather than an exercise: the problem, worked examples, and the solution in full. To type it out, the same problem runs in Python.
Where you start
int oeeScore(int availability, int performance, int quality) {
}Worked examples
| Call | Result |
|---|---|
oeeScore(90, 95, 99) | 85 |
oeeScore(100, 100, 100) | 100 |
oeeScore(0, 100, 100) | 0 |
oeeScore(150, 100, 100) | 100 |
Hint
Clamp all three first, then multiply and divide by 10000 — adding 5000 before the divide rounds it.
Reference solution in Java
int oeeScore(int availability, int performance, int quality) {
int a = Math.max(0, Math.min(100, availability));
int p = Math.max(0, Math.min(100, performance));
int qy = Math.max(0, Math.min(100, quality));
return (a * p * qy + 5000) / 10000;
