Embodiment Construction

[0034] The present invention will be further described below in conjunction with accompanying drawing.

[0035] The present invention comprises the following steps:

[0036] (1) Construct a competitiveness evaluation system for power generation enterprises.

[0037] Construct the competitiveness index system of power generation enterprises: (1) the target layer, which is to make a comprehensive evaluation of the competitiveness of power generation enterprises; (2) the criterion layer, which is divided into three levels, namely resource base, enterprise behavior, and enterprise performance; (3) ) indicator layer, that is, 13 evaluation indicators distributed on three levels: installed capacity, total assets, market share, human resources (number of college graduates or above), scientific research strength, power generation, equivalent availability coefficient, and average unit utilization hours Number, cost profit margin, on-grid electricity, return on equity, return on total ...

Abstract

A power generation enterprise competitiveness evaluation method based on combined weighting and improved TOPSIS, comprising the following steps: a. constructing a power generation enterprise competitiveness evaluation system; b. performing dimensionless standardization on evaluation indicators; c. passing subjective weights and objective weights to determine the index weights; d. Calculate the weighting matrix and translate the coordinate origin to the ideal solution point; e. Determine the negative ideal solution after translation And calculate the vertical distance between each evaluation scheme and the ideal solution ; f. According to the obtained vertical distance right Items to be evaluated are sorted, The smaller the value, the stronger the competitiveness of the corresponding power generation enterprises. The present invention applies the improved TOPSIS model based on combined weighting to the competitiveness evaluation of power generation enterprises, effectively reducing the deviation caused by over-reliance on subjective or objective weights in the decision-making process, and making the evaluation results closer to the reality. The evaluation method is simple, scientific and reasonable, and can accurately evaluate the competitiveness of power generation enterprises.

Description

technical field [0001] The invention relates to a method capable of accurately evaluating the competitiveness of a power generation enterprise, which belongs to the technical field of power generation. Background technique [0002] With the continuous deepening of power system reform, my country's power generation market has transitioned from monopoly to competition, and power generation companies have gradually become the main body of market competition and will face increasingly fierce competition. In this situation, it is very important for the survival and development of power generation enterprises to seriously study and analyze the factors affecting the competitiveness of power generation enterprises and comprehensively evaluate the competitiveness of power generation enterprises. [0003] In our country, since the 1990s, the competitiveness of enterprises has gradually attracted people's attention, so the evaluation of the economic benefits of enterprises in our count...
