6. Planering av produktflöden under en förändringsprocess
Sammanfattning : A central problem of this thesis is how to coordinate production and transport scheduling during an on-going improvement in order to achieve greater cost efficiency. The problem is analysed from the manufacturing company´s perspective, and one of the aims is to demonstrate the inter-dependency between the organization of production and transport. LÄS MER
7. On reliability-based design of rock tunnel support
Sammanfattning : Tunneling involves large uncertainties. Since 2009, design of rock tunnels in European countries should be performed in accordance with the Eurocodes. The main principle in the Eurocodes is that it must be shown in all design situations that no relevant limit state is exceeded. LÄS MER
8. Reliability-based design of rock tunnel support
Sammanfattning : Since 2009, design of rock tunnels can be performed in accordance with the Eurocodes, which allows that different design methodologies are applied, such as design by calculation or design using the observational method. To account for uncertainties in design, the Eurocode states that design by calculation should primarily be performed using the partial factor method or reliability-based methods. LÄS MER
9. Cathodic Arc Synthesis of Ti-Si-C-N Thin Films : Plasma Analysis and Microstructure Formation
Sammanfattning : This Thesis explores the arc deposition process and films of Ti-Si-C-N, inspired by the two ternary systems Ti-Si-N and Ti-C-N, both successfully applied as corrosion and wear resistant films. The correlation between cathode, plasma, and film properties are studied for a comprehensive view on film formation. LÄS MER
10. Uncertainty, variability and environmental risk analysis
Sammanfattning : The negative effects of hazardous substances and possible measures that can be taken are evaluated in the environmental risk analysis process, consisting of risk assessment, risk communication and risk management. Uncertainty due to lack of knowledge and natural variability are always present in this process. LÄS MER
