Sensor networks (SN) have arisen as one of the most promising monitoring technologies. So far the majority of SN deployments have assumed that sensors can be configured prior to their deployment because the area and events to monitor are well known at design time. Our concern is the extension of the theory of the Shapley value to problems involving externalities. Using the standard axiom systems behind the Shapley value for an arbitrary exogenous coalition structure leads to the identification of bounds on players' payoffs around an " externality-free " value. In endogenizing the coalition structure, we analyze a two …Math 1030 exam 1. Term. 1 / 51. ranking. Click the card to flip 👆.

The Shapley-Shubik power index is used because it is best suited to analysing the distribution of profits resulting from building a coalition (in our case, the profit is the influence on the final decision). We primarily seek methods for evaluating the prospects of individual players, and our results center around the class of “probabilistic” values (defined in the next section). In the process of obtaining our results, we examine the role played by each of the Shapley axioms in restricting the set of value functions under consideration, and we ...The Shapley–Shubik method (Shubik 1962) is an adaptation of the Shapley value to the case where the agents demand different quantities of (possibly …Our concern is the extension of the theory of the Shapley value to problems involving externalities.
