考虑市场占有率的面向服务互联网多准则均衡模型

研究了由多个服务提供商、多个网络运营商和多个需求市场构成的互联网, 建立了更一般的面向服务互联网均衡模型, 其中服务提供商提供不同质量的服务, 通过网络运营商供给需求市场的顾客下载或购买, 顾客根据服务产品的价格会随机地选择服务。不同的服务提供商之间关于服务数量和服务质量的Nash博弈在利润最大和市场占有率最大两个准则下达到均衡, 不同的网络运营商之间是关于服务价格的Bertrand博弈, 而服务提供商和网络运营商之间为Stackelberg博弈。利用均衡理论、二层规划理论和随机效用理论, 分析了各层成员的均衡条件以及服务提供商和网络运营商之间的均衡条件, 构建了考虑市场占有率的面向服务互联网多准则均衡模型, 即满足均衡约束的变分不等式问题。最后给出求解算法和算例说明模型的有效性, 以及市场占有率的权重指标对互联网各成员利润的影响。

Multicriteria equilibrium model of a server-oriented internet with the market share

A multicriteria equilibrium model of a server-oriented internet with quality competition consisting of the service providers, the network transport providers and the demand markets was designed. The service providers provide substitutable(but not quality identical) services to the demand markets by the net work transpert providers the custemers of the demand markets select the service randomly according to the price. The service providers compete with quantity and quality in a Nash manner to maximize their profits as well as their market share. The network transport providers compete with prices in a Bertrand manner. The two types of competition were unified in a Stackelberg game. The multicriteria equilibrium model of the server-oriented internet was established by variational inequality method based on the game theory bi-level programming and stochastic utility theory. Final, the algorithm were proposed and the numerical examples were solved to test the efficiency of the model and the effect of the market share.
