Generic Multi-Attribute Analysis (GMAA)

Abstract

The Generic Multi-Attribute Analysis (GMAA) System is a Decision Support System (DSS) based on an additive multi-attribute utility model that accounts for incomplete information concerning the inputs. The system is intended to allay many of the operational difficulties involved in the Decision Analysis (DA) cycle, which can be divided into four steps: structuring the problem (which includes specifying objectives, building a value hierarchy and establishing attributes for the lowest-level objectives); identifying the feasible alternatives, their impact and uncertainty (if necessary); quantifying preferences (which includes the assessment of the component attribute utilities as well as the value trade-offs); evaluating strategies and performing Sensitivity Analysis (SA).
