Multiple-criteria decision analysis
The Multi Criteria Analysis ( MCA), German as multi-criteria decision analysis is a class of methods for the analysis of decision-making or action possibilities in the context of decision theory.

The cost-benefit analysis (NWA ) was developed by Christof Zangemeister 1970. The action alternatives should be ordered here according to the preferences of a decision maker. The preferences are aggregated on the indication of utility values , each with a total value of an alternative.
