In the grid environment where the gird resources have different speeds of computation and prices,optimal time schedule problem based on budget constrain is discussed. A relevant algorithm is proposed. The task schedule problem is converted into a linear programming problem. Each resource gains the optimal execution time and the smallest completion time of the task under the condition of the budget constraint in the use of the simplex algorithm to obtain the approximate optimal solution. Simulation experimental results show the performance of the algorithm is superior to other similar algorithms.
