6. On Bayesian Decision Analysis for Evaluating Alternative Actions at Contaminated Sites
Sammanfattning : Today, contaminated land is a widespread infrastructural problem and it is widely recognised that returning all contaminated sites to background levels, or even to levels suitable for the most sensitive land use, is not technically or financially feasible. The large number of contaminated sites and the high costs of remediation, are strong incentives for applying cost-efficient investigation and remediation strategies that consider the inherent uncertainties.

7. Pipe failure assessment and decision support system for a smart operation and maintenance : A comprehensive literature review and a conceptual decision analysis model proposal
Sammanfattning : The reported research provides a rough guide to the best practice of decision modeling concerning urban pipeline systems’ rehabilitation. The thesis aims to bring attention to the fact that a proper decision-making model is a cornerstone for efficient infrastructure management. LÄS MER
8. Computational decision analysis
Sammanfattning : This thesis presents a new framework and a tool for decisionmaking using uncertan information. It is called DELTA after itsprimary decision rule. The objective is to present a method forevaluating choices under uncertainty. LÄS MER
9. Handling severe uncertainty in strategic project appraisal : Methods and applications of context analysis
Sammanfattning : The long-term success or failure of a strategic project is largely shaped by its context. Therefore, the assessment of the external factors influencing the fulfilment of project long-term goals is vital for the effective project appraisal and planning. LÄS MER
10. Imprecise information in multi-level decision trees
Sammanfattning : The information available to decision makers is often vague and imprecise, and various methods based on interval estimates of probabilities and utilities have been proposed to deal with this. The discussion has, however, mostly evolved around representation, and much less has been done to take into consideration the evaluation, and also computational and implementation aspects has been left out.
