ELECTRE TRI is a multiple criteria decision aiding sorting method with a history of successful real-life applications. ELECTRE TRI requires as input several parameters, such as criteria weights, thresholds, category profiles, and lambda cutting level. We propose the SMAA-TRI method for analyzing the stability of ELECTRE TRI analysis and for deriving robust conclusions. SMAA-TRI is based on Stochastic Multicriteria Acceptability Analysis (SMAA), and it allows ELECTRE TRI to be used with imprecise, arbitrarily distributed values for weights and the lambda cutting level. The method computes for each alternative action the share of parameter values that have it assigned to different categories. We list some potential military applications. To demonstrate SMAA-TRI, we re-analyze a case study in the field of risk assessment and management.
