While there are some obstacles to the use of computers in dispute resolution, their use is growing. A recent study identified 20 different situations in which computer models either have been used or are being developed for use. Computer-based models and simulations provide a means for collecting and categorizing scattered and diverse data, analyzing the interests of disputants, simulating the effects of proposed settlements, and identifying the best obtainable results for all parties. Computer simulations make possible sensitivity, decision-tree, case, and optimization-related analyses, and also provide a means for teaching negotiation and dispute resolution methods. Such models have been used in settling disputes over ocean mining, fishing rights, municipal financing, and compensation claims against the manufacturer of the Dalkon Shield intrauterine device. As computer models are increasingly used, new issues will arise, including the impact of models on bargaining, obstacles to the use of models, and how models can increase understanding of the negotiation process. 3 figures.
