Web1 de jun. de 2024 · Based on the classic Shapley value, we propose an weighted coordination approach. • Consider a supply chain consisting a manufacturer, a retailer and a remanufacturer. • Given fairness concerns, we focus on how to allocate the centralized-setting profit. • We prove that our model conditionally outperforms the classic Shapley … WebWe present new axiomatic characterizations of the symmetric Shapley value and of weighted Shapley values for transferable utility coalitional form games without imposing …
WebOn Weighted Shapley Values By E. Kalai I and D. Samet 2 Abstract: Nonwmmetric Shapley values for coalitional form games with transferable utility are studied. The … Web1 de jan. de 1995 · We revisit Kalai and Samet’s (1987) first characterization of the class of weighted Shapley values. While keeping efficiency, additivity, and the null player property from the original characterization of the symmetric Shapley value, they replace symmetry with positivity and partnership consistency.
Web11 de abr. de 2024 · The Shapley Value. The SV [Shapley, 1953] is a classic concept in cooperative game theory to attribute the total gains generated by the coalition of all players. At a high level, it appraises each point based on the (weighted) average utility change caused by adding the point into different subsets. Webpi.shapley Power based on the Shapley-Shubik index. Description This function determines the distribution of the power based on the Shapley-Shubik index and the Owen value. Usage pi.shapley(quota, weights, partition = NULL) Arguments quota Numerical value that represents the majority in a given voting.
WebThe intersection of these two families consists essentially of the symmetric Shapley value. These families are also characterized by a prObabilistic arrival time to the game approach. It is also demonstrated that lack of symmetries may arise naturally when players in a game represent nonequal size constituencies. 1 Keyphrases
