摘　　要：针对网格计算中信息反馈机制或者信息传递机制因网格结点多、弧数量及考虑重点变化大、反馈路径和信息传递路径选择难度大的问题,提出一种基于优势比及路径期望的方法,对网格下的信息反馈问题进行建模,利用求解算法解出最优值。实验表明,该模型及求解算法在大规模网格信息反馈或者信息传递过程中能求得最优解,而且迭代次数与时间开销将趋于最优。According to the problems of multi-node in grid,arc number and great changes of considered emphases,path selection of feedback and information transfer were difficult,a method based on priority comparison and path expectation was put forward to model for the problem of information feedback under grid and solved optimal value by using solution algorithm.Experiments show that the model and solution algorithm in large-scale grid feedback or information transmission process can get the optimal solution,and the number of iterations and time complexity will tend to the optimal.
