    Dear colleagues:

    You are invited to DAS Webinar, which features Prof. Eeva Vilkkumaa, an assistant professor of Management Science at the Department of Information and Service Management at Aalto University School of Business, Finland. She received her doctoral degree in 2014 at the Department of Mathematics and Systems Analysis at Aalto School of Science. Her research interests include multicriteria decision analysis, portfolio decision analysis, scenario methods, strategic foresight, behavioral decision theory, and applications to healthcare and strategy development. She has 18 years of experience in teaching courses on operations research, business analytics, and strategic foresight at Aalto University and Aalto Executive Education and Professional Development. Vilkkumaa has published in leading scientific journals such as Management Science, Operations Research, and European Journal of Operational Research. She is an Editorial Board member of the Journal of Multicriteria Decision Analysis. She has also been a partner and consultant in two companies specializing in the use of mathematical modeling for decision support and strategy development: Decision&Action (2016-) and Swanlake Strategy (2020-2024).

    Abstract: Companies pursue their goals by selecting and implementing a combination or portfolio of actions that consume resources. The extent to which these actions help attain the companies' objectives is often contingent on whether a given future scenario is realized. We present a model-based framework for supporting the selection of a portfolio of actions that is robust across different scenarios while accounting for the impacts that the actions may have on the probabilities of these scenarios. For the purposes of this framework, we develop a new portfolio decision analytic model and algorithms to help generate recommendations for selecting actions, when (i) the actions' scenario- and objective-specific impacts as well as preferences between the objectives are incompletely specified, and (ii) information regarding scenario probabilities is incomplete and may depend on the selected actions. The framework is applied in a high-impact case on supporting the strategy process at the payments unit of Nordea Bank Abp, the largest retail bank in the Nordic countries.

    This event will take place virtually on Thursday, August 28th, 9AM PT / 12PM ET / 6PM CET. Please find below the link to register your name and email address.
