Comprehensive evaluation method and device for county-level power supply enterprises under the background of fine management

Abstract

The invention discloses a comprehensive evaluation method and a device for a county-level power supply enterprise under the background of fine management, which comprises the following steps: selecting evaluation criteria and obtaining a plurality of evaluation indexes; The combination weight value of evaluation criterion is obtained by combinatorial optimization method. Obtaining a relative evaluation value of the evaluation index based on an adversarial data envelopment cross analysis method; Weighting the comprehensive weight value and the relative evaluation value to obtain a static crossevaluation value; Setting up the appraisal cycle and calculating the static cross-evaluation value of each year in the appraisal cycle of the power supply enterprise; The time series weighted vector is determined based on information entropy and time degree, and the static cross-evaluation value of each year is weighted linearly based on time series weighted vector, and the dynamic comprehensive evaluation value is obtained. According to the dynamic comprehensive evaluation value, the reward and punishment coefficient of the power supply enterprise is established. This method has strong advantages in unifying evaluation criteria, harmonizing subjectivity and objectivity, identifying weak links, and is suitable for indirect competition among monopoly enterprises in different regions.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to a comprehensive evaluation method and device for county-level power supply enterprises under the background of refined management. Background technique [0002] In recent years, with the gradual implementation of the State Grid Corporation's "three sets and five major" management strategy and the deepening of the power system reform, the company's management concepts, management methods, and management requirements have been fully extended to grass-roots power supply enterprises. County-level power supply enterprises have become lean The main body of management is affected by various factors such as management system, personnel structure, equipment level, business philosophy, etc., and its development is extremely unbalanced. The data span of key indicators of production and operation is very large. It is difficult to conduct macro quantitative analysis on the long-term deve...

Problems solved by technology

[0007] However, the existing evaluation strategies lack the consideration of the trade-off between subjective expert opinion and objective data information on the one hand.

The subjective weighting method depends on the preference of decision makers, and the weight determination is relatively one-sided; the objective weighting method depends on the degree of dispersion of the index data, and the weight determination is difficult to reflect the meaning of the index itself, and the adaptability is poor

On the other hand, there is a lack of collection of dynamic information, and most of the research relies on the analysis and evaluation of the data of a single year. The evaluation results are difficult to reflect the technical problems of the development trend of the enterprise.
