Energy transformation efficiency evaluation model establishment method based on non-radial DEA (Data Envelopment Analysis)

Abstract

The invention discloses an energy transformation efficiency evaluation model establishment method based on non-radial DEA (Data Envelopment Analysis). The method comprises the following steps that: carrying out positive and negative distinguishing on a model, and constructing a non-radial DEA model which is negative index-oriented; and adding a positive index into the model, and increasing corresponding index weight to form a bidirectional non-radial DEA model which comprises the negative index and the positive index. By use of the method, index orientation is distinguished to correctly highlight the influence of the negative index and the positive index for an efficiency value calculation result, and the objectivity and the reference value of a calculation result are improved. The calculation difficulty of the DEA model is lowered, and meanwhile, the algorithm applicability of the model is kept. The weight is added to the negative index and the positive index to lower the calculationdifficulty of the improved model, meanwhile, the inherent linear planning characteristics of the DEA model are kept, and most linear planning solving algorithms are still suitable for the non-radial DEA models. The model indexes are subjected to positive and negative distinguishing, the non-radial DEA model which is negative index-oriented is constructed, the positive index is added into the model, the corresponding index weight is increased, and the bidirectional non-radial DEA model which comprises the negative index and the positive index is formed.

Description

technical field [0001] The invention relates to the technical field of energy transition efficiency evaluation, in particular to a method for establishing an energy transition efficiency evaluation model based on non-radial DEA. Background technique [0002] In terms of research objects, sufficient, reliable, safe, and low-carbon energy supply is the key support and important guarantee to ensure the smooth completion of the conversion of new and old kinetic energy. Therefore, energy supply should be transformed from the previous fossil energy supply system dominated by coal, oil, and natural gas to a new energy supply system dominated by renewable energy such as wind and light. inner requirements. In the current research at home and abroad, there are many researches on the implementation path and safeguard measures of the conversion of new and old kinetic energy, about how to carry out energy transformation, provide more powerful energy support for the conversion of new and...

Problems solved by technology

[0003] In terms of model construction, the traditional DEA model (Data Envelopment Analysis, DEA) uses the same calculation for positive indicators (the larger the value, the better) and negative indicators (the smaller the value, the better) However, the impact of positive indicators and negative indicators on the final efficiency is different. This calculation method without clear distinction in the current DEA model will reduce the objectivity and scientificity of the calculation results

However, if the indicators are differentiated, the difficulty and complexity of the calculation may be significantly increased
