A score value describes how far the actual value differs from the target value given by the golden cip. The value is always between 0 and 100. With 100 being an exact match and 0 meaning that the actual value is further than 1 target value from the target value away. The calculation is based on the following scores:
-
Overall Score
The overall score is the average of the time score and the part scores. -
Time Score
To create the time score the duration of the cip is compared with the duration of the golden cip. -
Part Scores
The trend of the cip is compared to the trend of the golden cip. The comparison is based on the Sinner's circle and consists of the following four components:- Temperature
- Concentration
- flow rate For the comparison trend values with a resolution of one minute are used.
-
Additional Scores
For each additional parameter a single additional score is being calculated. This is done by calculating a single value for the whole cip sequence. This value is than compared with value from the golden CIP.
When sequence scoring is used a single score is calculated for the whole time frame. For the time score the sequence time is compared, for trends the whole trend is compared at once. When step scoring is used the sequence is divided into multiple steps. And each step is score individually and from these scores the final score will then be calculated, with each step having the same importance. The benefit of this method is that each step in the cip is only compared to the corresponding step in the golden cip. This leads to a higher accuracy in the score calculation.
