After the formalization of the RMA problems, methods for normalizing the original stochastic decision matrix are proposed. For discrete RMA problems, the concepts of C-type solution and S-type solution are defined, and the inclusion relations between different sets of solution in the same type and between different sets of solution in different types are concluded. For continuous RMA problems, the decision analysis based on Dα-dominance relation is illustrated.
