Decision-making often refers to ranking alternatives based on many involved criteria. Since the introduction of the Analytic Hierarchy Process (AHP) in 1980, pairwise comparisons of criteria have a long tradition in multi-criteria decision-making.

Sie unterscheiden sich dadurch von stark strukturierten, stets wiederholbaren Routineprozessen. In Abhängigkei...
How can we reduce the required effort to develop certified programs in proof assistants such as Coq? A major trend is to introduce untrusted oracles able to justify their answers by producing a certificate, i.e. a witness of their computations. A trustworthy result is then built from this certificate by a certified checker. This alleviates the burd...

A minimization of disturbance caused by aircraft noise events and a reduction of fuel consumption during the initial and final phase of flight. These are the two objectives that play an important role in the Flexible Runway Allocation Model. By taking into account fuel consumption alongside noise annoyance, this model enables to analyze and optimiz...

While concerns about global warming have never been so important, one of its first causes: global electricity consumption, is still growing. One way to stem the phenomenon could be to better balance demand and production, in order to switch on less big production groups and to allow the integration of more renewable production sources. The new para...
