基于Gridsim的经济网格组合双拍卖模型实现与研究

his paper is researching the implementation schema of combinatorial double auction in economic Grid by providing two different kinds of combinatorial double auction models which are based on central-proxy mode and distribution mode separately. In central-proxy mode, bid information is not known for the users in Grid. A central-proxy is used for the process of pricing and task distribution. And in distribution mode, contrarily, bid information is all known for the users in Grid. So a central-proxy is not needed, and instead user nodes implement these functions. Besides, an improved genetic algorithm by adding deteriorative solutions with a certain probability is used to decide the winning bid for the auction. Finally, experiment of the combinatorial double auction of two different modes is implemented by the simulation tool Gridsim. And the data results validate the effectiveness of the combinatorial double auction based on these two modes, also it can be extended well to the more fields.
