The utility analysis takes place u. a. Application in controlling, in project management and in investment decisions, just wherever an assessment based on several quantitative and qualitative criteria, goals or conditions must be made.
The CBA is the “analysis of a set of complex alternative actions with the purpose of ordering the elements of this set according to the preferences of the decision-maker regarding a multidimensional target system. The order is mapped by specifying the utility values (total values) of the alternatives.
