Customer churn rate / attrition rate: prediction of customer loss

2019
Χαμένη πελατεία ορίζεται συνήθως η πιθανότητα ένας πελάτης να διακόψει εθελοντικά ένα υπάρχον/ουσα συμβόλαιο-σύμβαση μέσα στους επόμενους Χ μήνες, όπου ο αριθμός Χ καθορίζεται σύμφωνα με τον τύπο της επιχείρησης και το είδος του προβλήματος πιο συγκεκριμένα. Αναφέρεται επίσης και ως απώλεια πελατών. (Forecast Analytics,2015).

A Model for the Prediction of Churning Losses in Geared Transmissions—Preliminary Results

Journal of Mechanical Design, 2006
A series of formulas are presented which enable accurate predictions of churning losses for one pinion characteristic of automotive transmission geometry. The results are based on dimensional analysis and have been experimentally validated over a wide range of speeds, gear geometries, lubricants, and immersion depths.

Optimization of Oil Quantity in Manual Transmission and Reducing Churning Loss

SAE Technical Paper Series
<div class="section abstract"><div class="htmlview paragraph">The gearbox is a crucial aggregate in a diesel truck. Gearboxes must work efficiently to get the job done properly and lubrication is vital to this efficiency. Lubricating oil is like the circulation system of a gearbox.

A Novel Prediction Model for Churning Power Loss of Spur Gear

Lubrication Science
ABSTRACTThe prediction of churning power loss has been a difficult problem in the analysis of spur gears. Thus, an analytical prediction model based on the redefinition of churning power loss and energy transformation is proposed to estimate the churning power of spur gears. Churning power loss is defined as the combination of the power loss due to the
