Defence of dissertation in the field of systems and operations research, MSc Alessandro Mancuso, 18.9.2020

3. September 2020

Title of the dissertation is "Risk-informed optimization of mitigation strategies in safety-critical systems"

The performance of industrial systems can be compromised due to multiple risks, caused by accidents and threats. Such risks may result in system failure, which leads to safety, financial and environmental consequences. For this reason, industrial organizations need to invest in the design and operations of their production systems in order to improve the reliability, availability, maintainability and safety of their systems.

This dissertation proposes an innovative framework to assess and select risk mitigation strategies in the design and operations of systems, based on the minimization of risks of the overall system. In this framework, the analysis of systemic risks integrates component-based analyses to manage the industrial system optimally while satisfying budget and technical constraints. The applicability of this framework is illustrated by re-examining case studies which have been previously analyzed in literature as well as by presenting new real-life case studies based on statistical data and expert judgement.

The methodological and computational results of the dissertation can be readily adapted to develop further applications in other areas of industrial activity.

The title of the dissertation is "On Decoding Problems, Lattices and Generalized Concatenated Codes"

Reliable and efficient information transfer is one of the building blocks of today’s interconnected society. With more devices connected every day, the importance of reliable communication is constantly growing. Wireless networks are used everywhere and they are evolving at a rapid pace. The remarkable innovation and improvement in performance we have seen during the last decades is obviously a result of technological advances in many fields. However, none of this would be possible without information theory, and more specifically, coding theory.

One of the problems that coding theory deals with is: how can we achieve reliable and efficient communication over an unreliable channel. The answer is so-called error-correcting codes. In this thesis we study different types of error-correcting codes and so-called decoding algorithms for these codes. We improve known decoding algorithms for several classes of codes. This is important work, since there are many known good classes of error-correcting codes that cannot be used in practical applications due to impractical and/or slow decoding algorithms.

Summer 2021 Bridges conference

16. December 2019
Due to the covid-19 pandemic we will not be able to hold the Bridges Conference planned for Aalto University in August 2020.  We will continue to process the papers for the Proceedings as planned, so authors of accepted papers will have their work officially recognized as reviewed and published.  There will be a new paper cycle for the next Bridges Conference in the summer of 2021. More information can be found on the conference website.
