1. On maintenance optimization for offshore wind farms
Sammanfattning : The maintenance cost is known to be an important part of the levelized cost of energy generated by wind parks. Operational costs can be significantly reduced by optimizing decisions for maintenance strategies, maintenance support organization and maintenance planning. LÄS MER
2. Reforming a publicly owned monopoly : costs and incentives in railway maintenance
Sammanfattning : The railway system is often considered to be an industry where a monopoly occurs “naturally”, which can explain the public ownership and the use of regulations. However, railways in Europe have been subject to reforms during the last three decades. LÄS MER
3. Continuous Preventive Bridge Maintenance : Effect of High Pressure Washing on Concrete Bridges
Sammanfattning : In Sweden, as in many other countries, preventive maintenance of structures andbridges is considered important. It provides several benefits such as prolonged lifespan or service life, less need for repair, and hopefully reduced costs and lowerenvironmental impact.A large part of Sweden’s bridge stock is getting quite old.

4. Two-Level Multi-Objective Genetic Algorithm for Risk-Based Life Cycle Cost Analysis
Sammanfattning : Artificial intelligence (AI) is one of the fields in science and engineering and encompasses a wide variety of subfields, ranging from general areas (learning and perception) to specific topics, such as mathematical theorems. AI and, specifically, multi-objective genetic algorithms (MOGAs) for risk-based life cycle cost (LCC) analysis should be performed to estimate the optimal replacement time of tunnel fan systems, with a view towards reducing the ownership cost and the risk cost and increasing company profitability from an economic point of view.

5. Data-driven models for railway track geometry maintenance
Sammanfattning : Railways are currently experiencing higher demands on safety, infrastructure performance, network capacity and service quality, etc. As a result, a high level of track availability, service quality and infrastructure robustness against unexpected events is required, at reduced cost, to meet the demands.
