Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose an evolutionary dynamics for multicriteria games based on the ordered weighted average (OWA) of payoff differences of all criteria, and investigate its properties. Multicriteria evolutionary games model interactions among many decision makers who choose strategies on the basis of multiple criteria. We consider a stochastic imitation model that the decision maker imitates opponent's strategy with a probability that depends on the OWA of the payoff differences between them in a large population of decision makers. Then, as evolutionary dynamics for multicriteria games, we derive mean dynamics that is a deterministic approximation of the dynamical stochastic behavior of the population. We also investigate relationship between equilibrium points of the dynamics and equilibrium concepts of multicriteria games such as weak equilibrium and evolutionary stability under several weights of OWA operator.
