Abstract

The Shapley value, one of the most widespread concepts in operations Research applications of cooperative game theory, was defined and axiomatically characterized in different game-theoretic models. In this paper we provide a new axiomatization of the Shapley value which probably is the most important one-point solution concept for the cooperative games using a differential marginality axiom. This axiom states that two players’ payoff differential is completely determined by the differences of their marginal contributions. Efficiency means that the worth generated by the grand coalition is fully allocated to the players. Null player property means that the marginal contributions of null players in a game are zero payoffs. In this study we show that the Shapley value is redefined by efficiency axiom, the null player property and differential marginality axiom.

Abstract

İşbirlikçi oyun teorisinin yöneylem araştırması uygulamalarındaki en yaygın kullanılan çözümlerinden biri olan Shapley değeri farklı oyun teorisi modellerinde tanımlanmış ve aksiyomatik olarak karakterize edilmiştir. Bu makalede diferansiyel marjinaliti aksiyomu kullanılarak işbirlikçi oyunlardaki en önemli çözüm kavramlarından biri olan Shapley değeri için yeni bir karakterizasyon verilecektir. Bu aksiyom, iki oyuncunun ödeme farklılıklarının sadece marjinal katkılarının farklılıklarına bağlı olduğunu göstermektedir. Verimlilik aksiyomu, oyuncuların ödemelerinin toplamının büyük koalisyonun ödemesine eşit olması olarak tanımlanmaktadır. Null oyuncu özelliği, bir oyunda null oyuncu varsa bu oyuncunun oyuna herhangi bir katkısı olmaması demektir. Bu çalışmada, Shapley değeri verimlilik aksiyomu, null oyuncu özelliği ve diferansiyel marjinaliti aksiyomları ile yeniden tanımlanacaktır.
