We examine agent failures in weighted voting games. In our cooperative game model, R-WVG, each agent has a weight and a survival probability, and the value of an agent coalition is the probability that its surviving members would have a total weight exceeding a threshold. We propose algorithms for computing the value of a coalition, finding stable payoff allocations, and estimating the power of agents. We provide simulation results showing that on average the stability level of a game increases as the failure probabilities of the agents increase. This conforms to several recent results showing that failures increase stability in cooperative games.
