Sigma-Mu efficiency analysis: A new methodology for evaluating units through composite indices -- Talk by Menelaos Tasiou Event

Event details

Composite indicators have gained astounding popularity in a wide variety of research areas. Their adoption by global institutions has further captured the attention of the media and policymakers around the globe, and their number of applications has surged ever since. Yet crucial aspects in their construction, such as the weighting of the elementary indicators, raise a flag on whose preferences are taken into account, with phenomena of `manipulation’ being always present. `Sigma-Mu’ is a method proposing a more holistic and objective evaluation of DMUs to the traditional alternatives, while it encapsulates uncertainty techniques that are usually found to be missing despite their very importance. Its background is based on renowned OR methods aiding towards a more transparent evaluation in the hands of decision-makers.
