检测服务提供商联盟
Detecting service provider alliances
摘要：
我们提出了一个算法检测服务提供商联盟。要做到这一点，我们建模的竞争对手的服务提供商的合作博弈模型。编排（对等服务组合模型）需要一组服务来满足其需求。对于每个需求，用户必须选择将使用哪些服务提供者以最低的成本执行编排。由于缺乏集中化，供应商可以结成联盟来控制市场。我们提出了一种新的算法，能够检测服务提供商之间的联盟，根据我们的研究结果表明，这个游戏有一个空的核心，但非空的讨价还价集。
英文摘要：
We present an algorithm for detecting service provider alliances. To perform this, we modelize a cooperative game-theoretic model for competitor service providers. A choreography (a peer-to-peer service composition model) needs a set of services to fulfill its requirements. Users must choose, for each requirement, which service providers will be used to enact the choreography at lowest cost. Due to the lack of centralization, vendors can form alliances to control the market. We propose a novel algorithm capable of detecting alliances among service providers, based on our findings showing that this game has an empty core, but a non-empty bargaining set.
