Study on optimizing deployment of roadway excavation equipment based on DEA

On the basis of introducing Data Envelopment Analysis, 12 samples of a coal group company were analyzed with the mathematical model. The expected output could indeed be achieved after adjusting investing in equipment according to results of data analysis, and the output was consistent with the actual situation. The results showed that: data envelopment analysis was used to optimize deployment of coal tunneling equipment, significantly increasing the rate of roadway excavation.
