This paper carries out linear planning for school affairs information, aiming to optimize the allocation of school affairs information resources and achieve the goal of school affairs informationization. Based on the content of school affairs information, current problems and the necessity of resource allocation, this paper constructs a linear planning model, based on which a dyadic model is established to construct a school affairs information resource allocation model based on linear planning. Through relevant experiments. Test the resource allocation effect of this paper’s model. The average number of cases of this paper’s model to solve the optimal solution is comparable to other algorithms, but the computation time is significantly shorter than that of other algorithms, which has a greater advantage of speedy solution degree. In the experiments of small-scale and large-scale problems, the resource allocation model based on linear programming in this paper has the lowest relative deviation index, and has the most excellent effect in solving the optimal solution.
