Commerce efficiency comprehensive evaluation method based on small-wave network method

Abstract

The invention relates to a commerce efficiency comprehensive evaluation method based on a small-wave network method. The method comprises the following steps that 1) an efficiency item comprehensive evaluation index system is established; 2) each item index value of the comprehensive evaluation index system is computed; 3) the best weight of each index is determined with the small-wave network method; 4) comprehensive evaluation values of alternative schemes are computed, and the best scheme is output. Network parameters wij, rj, bj and aj are computed in an iterative mode with the small-wave network method, and accordingly the parameter value which is closest to the expert score of each training scheme is found, finally, the comprehensive evaluation results of the efficiency schemes are obtained, different characteristics of different schemes are integrated, advantages and disadvantages of the schemes are measured comprehensively, quantitative evaluation results are obtained, and therefore an item decision maker can directly compare the overall advantages and disadvantages of the schemes and select the efficiency schemes. The small-wave network method is used in commerce efficiency comprehensive evaluation, computing errors are small, and convergence speed is high.

Description

technical field [0001] The invention relates to the field of comprehensive evaluation methods for energy efficiency projects, in particular to a comprehensive evaluation method for commercial energy efficiency based on wavelet network method. Background technique [0002] The purpose of comprehensive evaluation of energy efficiency projects is to measure the expected contribution effect of the proposed project to investors, power grid companies, end users and the whole society, and to clarify the relevant economic, environmental and social benefits that the project can bring. Evaluation indicators are the basis for the above-mentioned scientific evaluation. [0003] At present, the evaluation methods of energy efficiency projects in the industrial and building fields are relatively mature. Commonly used production equipment in small and medium-sized enterprises, such as boilers and steam systems, motor systems such as water pumps, fans and air compressors, lighting systems, ...

Problems solved by technology

[0004] Similar to this, the existing energy efficiency evaluation indicators in the commercial field are often limited to the power-saving capabilities of each end-use equipment, such as the energy efficiency evaluation of air conditioners, refrigerators, washing machines, and transformers, without considering the impact on investors after the implementation of energy efficiency projects , the economic, environmental and social benefits of the power grid company, or the corresponding quantitative value has not been set, so that there is no unified evaluation standard for each energy efficiency scheme, and the energy efficiency characteristics of a certain project reflected by various independent energy efficiency indicators cannot provide project information.
