Goal: The objective is to harmonise Swedish-English asset management definitions and to apply SCB’s (Statistics Sweden) data quality framework on maintenance records of the Swedish rail infrastructure.
Project status and results: The project aims to harmonise Swedish-English asset management definitions and to assess operation and maintenance data quality within rail transportation. A prestudy was carried out on maintenance records of Trafikverket, to assess the benefit of maintenance inspections in terms of avoided failures in rail infrastructure. Results were positive, but due to uncertainties in data quality, the proposed method could not be recommended for implementation. Data quality issues concerned data bases, terminology usage and work order processes. With improved data quality control, data analysis and decision making processes can become more effective, which brings us to the project aim as stated above. The work includes SCB and Eurostat data quality frameworks.
