  1. 6. On Bayesian Decision Analysis for Evaluating Alternative Actions at Contaminated Sites

    Författare :Jenny Norrman; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; influence diagrams; Bayesian decision analysis; groundwater; data worth analysis; contaminated sites; decision analysis; risk analysis;

    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.

  2. 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

    Författare :Roya Meydani; John Leander; Andreas Lindhe; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Urban pipeline systems’ rehabilitation; Infrastructure management; Decision-modeling; Decision analysis; Problem structuring; Uncertainty; Bayesian decision theory; Utility-based decision-making.; Urbana ledningssystemsunderhåll; Infrastruktur förvaltning; Beslutsmod- ellering; Beslutsanalys; Problembeskrivning; Osäkerhet; Bayesiansk beslutsteori; Nyttobaserad beslutsmodell; Bro- och stålbyggnad; Structural Engineering and Bridges;

    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

  3. 8. Computational decision analysis

    Författare :Mats Danielson; KTH; []
    Nyckelord :;

    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

  4. 9. Handling severe uncertainty in strategic project appraisal : Methods and applications of context analysis

    Författare :Anton Talantsev; Aron Larsson; David Sundgren; John Ward; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Decision Intelligence; Deep Uncertainty; Scenario Analysis; Multiple Criteria Decision Analysis; Simulation; Context Analysis; Project Appraisal; Risk Assessment; Threat and Opportunity; Computer and Systems Sciences; data- och systemvetenskap;

    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

  5. 10. Imprecise information in multi-level decision trees

    Författare :Jim Johansson [Idefeldt]; Love Ekenberg; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multi-level; decision tree; decision analysis; decision tool; imprecise; Computer science; Datavetenskap;

    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.
