Aspekt sytuacji status quo we wspomaganiu wielokryterialnego wyboru bazującego na teorii gier

In this paper multiple criteria decision problem is considered as a noncooperative game. Each criterion is assigned with a player and every feasible (and effective) solution with a pure strategy. Players payoffs result from assessments of solutions in game state where every player chooses the same strategy-solution. In the analysed game status quo situation is a state in which at least one player-criterion chooses different strategy. The problem of payoff definition in such situation is considered in the paper. A proposal is to state pessimistic payoffs in status quo situations as minimal value of payoffs in situations related with considered solutions of multiple criteria problem (exactly multiple criteria choice problem). The proposal is compared with a deterministic model and solution and based on example from Madani and Lund's (2011) work.
