Abstract: Informatization construction is an important way to promote the development of metallurgical mining enterprises.Evaluating the informatization level of metallurgical mining enterprises reasonably and effectively is an effective way to promote the speed and level of enterprise informatization construction.Based on the PSR model, a system framework of informatization construction of metallurgical mining enterprises is proposed in this paper.The evaluation system of informatization level of metallurgical mining enterprises is designed, which has the characteristics of “pressure-state-response” system.The weight of each index is determined by the combination of AHP and entropy weight method.The evaluation model is used to verify the informatization development level of three metallurgical mining enterprises.The evaluation results are consistent with the actual informatization level of three enterprises, providing references and theoretical basis for promoting the informatization construction of metallurgical mining enterprises.
