The new game theory in operations research applications lies in the study of organizations and in systems that involve individuals, networks, and institutions. This important technique of operation research provides a basis for determining under specified conditions, the particular strategy that will result in maximum gain or minimum loss. Game theory is divided into two main branches. trailer This research aims to fill this gap using evolutionary game theory and quantitative simulation analysis [23, 24]. 0000022629 00000 n Image Guidelines 4. startxref Examples include negotiations between management and the … In the same way in competitive market, two or more parties make decisions with conflicting interest and action of one depends on the opponent task. 2. endstream Then the problem of game theory is solved by probability theory. Game theory is a model of decision making and strategy under differing conditions of uncertainty.
