Research on Evaluation Method of ERP Management System Application Efficiency

In order to strengthen the interactive relationship between enterprise management practice and information system, and realize the correct evaluation of enterprise ERP management efficiency, this paper puts forward a scheme of using neural network model to predict the implementation effect of ERP. On the basis of defining the research scope and task of ERP implementation diagnosis model, we adopt BP neural network evaluation method which can ensure the objectivity of diagnosis. Firstly, the enterprise management decomposition and ERP software decomposition scheme are proposed, and the system evaluation index system is established. Then, during the implementation process, GA is used to evaluate the line subsystem, and each system is ranked according to the evaluation score to find the weakest subsystem. Finally, through a specific application example, to evaluate the implementation effect of ERP in a manufacturing industry, it proves that the results are more efficient and practical, which is of great significance to promote the informatization construction of enterprises in China.
