Pareto analysis of the failure rate of passenger railway wagons

This article analyses the failure rate of railway passenger wagons operated in Slovakia from 2018 to 2019 through Pareto analysis. The aim is to identify the most faulty wagons regarding the number and duration of faults in the monitored period. The article contains a simple and multiple Pareto analysis. A description of individual types of wagons, their technical characteristics, and the analysis results in the form of Pareto diagrams are also included. Pareto diagrams visualise the number and frequency of failures. This approach provides an effective decision-making tool for maintenance and quality management in rail transport.
