2. RAMS and LCC in rail track maintenance
Sammanfattning : Railway infrastructure is a complex system. An important aspect of the rail infrastructure is that the assets have a long useful life. So once installed, it is very difficult to modify the initial design. Thus, the performance of the infrastructure depends on the maintenance and renewal decisions taken during its life cycle. LÄS MER
3. Maintenance decision support models for railway infrastructure using RAMS & LCC analyses
Sammanfattning : Today's railway sector is imposing high demands for service quality on railway infrastructure managers. Since railway infrastructure has a long asset life, it requires efficient maintenance planning to perform effectively throughout its life cycle to meet these high demands. LÄS MER
4. Kvinnors försörjningsrum : Hegemonins förvaltare och murbräckor

One strategy is to start a business of one's one, a strategy supported and called for by the Swedish Government, especially during the 1990s economic recession. LÄS MER
5. Link and effect model for performance improvement of railway infrastructure
Sammanfattning : Railway traffic has increased over the last decade and it is believed to increase further with transportation shifting from road to rail, due to rising energy costs and the demand to reduce emissions. To manage railway infrastructure assets effectively against agreed-upon and set objectives, performance must be measured and monitored. LÄS MER
