Query: Using the WOWA operator in robust discrete optimization problems   In this paper a class of discrete optimization problems with uncertain costs
is discussed. The uncertainty is modeled by introducing a scenario set
containing a finite number of cost scenarios. A probability distribution in the
scenario set is available. In order to choose a solution the weighted OWA
criterion (WOWA) is applied. This criterion allows decision makers to take into
account both probabilities for scenarios and the degree of pessimism/ optimism.
In this paper the complexity of the considered class of discrete optimization
problems is described and some exact and approximation algorithms for solving
it are proposed. An application to a selection problem, together with results
of computational tests are shown.
