摘要: Abstract Energy efficiency data from ethylene production equipment are of high dimension, dynamic and time sequential, so their evaluation is affected by many factors. Abnormal eliminated through consistency test, making the consumption uniform to improve comparability data. Due limit input output decision unit in envelopment analysis (DEA), energy same technology a certain year disposed monthly using DEA. The DEA weighted fused analytic hierarchy process. different technologies evaluated relative effectiveness find direction saving reduction.
