The Optimization of Grey Verhulst Model

摘要：

If some components of original sequence were regarded as the initial condition of the grey model, the time response function was optimized because of the problem that it couldn’t guarantee the best fitting between the original sequence and simulation sequence.In this paper, we first used the method of least square estimate to find the solution of the parameter c in the time response function of Verhulst model. Then we created the optimization model for the time response function of Verhulst model. Finally, the practicality and the validity of the model was proved by a real project and the simulation and prediction accuracy was improved in the project.
