A probabilistic analysis of inspection orders for Scania trucks (English)
Abstract [sv]

Denna rapport utreder huruvida det är mer eller mindre sannolikt att äldre fordon som använder Scanias serviceavtal Tillsynsavtal får ett föreläggande vid besiktning.. Den utreder också om en eller era påbyggnationer, så som kran, tipp, lyft och vinsch, på en lastbil kan ha en inverkan på sannolikheten att en lastbil får ett föreläggande. Två hypoteser har formulerats och utretts med hjälp av logistik regressionsanalys. Resultaten visar att det ar mindre sannolikt att äldre fordon som använder sig av serviceavtalet får ett förläggande. Lastbilar med era typer av påbyggnationer kan både vara mer och mindre sannolika att få ett förläggande (beroende på kombination). Lastbilar med endast en typ av påbyggnation kan dock ej påvisas vara mer eller mindre sannolika att få ett föreläggande vid besiktning.

 

Abstract [en]

This report investigates whether it is more or less likely that older vehicles using one of Scanias maintenance contracts Tillsynsavtal receives an inspection note. It also investigates if one or multiple types of superstructures, such as cranes, dumps, hoists and winches, on a truck might have an impact on the probability that the truck receives an inspection note. Two hypotheses has been formulated and investigated by logistic regression. The results show that it is less likely that an older vehicle using the maintenance contract receives an inspection note. Trucks with multiple superstructures can both be more and less likely to receive an inspection note (depending on the combination). Trucks with just one type of superstructure can however not be shown to be more or less likely to receive an inspection note.
