Problems solved by technology

In addition, the weight calculation methods of various indicators rely too much on human factors such as expert scoring to determine the weight of the indicators. It is difficult to unify the criteria for determining the weight of the indicators, and it is difficult to guarantee the scientificity and accuracy of the calculation results.

Embodiment

[0097] Taking the "power grid structure" index in the evaluation index of rural power grid transformation and upgrading project as an example, the process of calculating the weight of the index is explained by using the analytic hierarchy process.

[0098] (1) Subjective weight calculation

[0099] 1) Construct a judgment matrix based on a single expert score:

[0100] The "power grid structure (B)" indicators include "35kV and above substation dual power ratio (B1)", "35kV and above substation N-1 pass rate (B2)", "10 (20) kV line N-1 pass rate ( B3)", "Contact ratio of 10 (20) kV main line in the county (B4)", "Qualification rate of power supply radius of 10 (20) kV main line (B5)" 5 three-level sub-indicators".

[0101] In the form of expert scoring, according to the 1-9 scale method, the above five indicators are compared and scored in pairs, and the judgment matrix is ​​formed as follows:

[0102] Table 3 Judgment matrix of power grid structure three-level indicators

Abstract

The present invention relates to a method for determining the weight of evaluation indicators for rural power grid transformation and upgrading projects. The method firstly uses the analytic hierarchy process to determine the subjective weight; The subjective and objective weights are multiplicatively integrated to establish the final index weight, which not only avoids the influence of subjective deviation but also fully reflects the objective actual situation, which can effectively improve the scientificity and accuracy of index weight assignment.

Description

technical field [0001] The invention relates to a method for determining index weights, in particular to a method for determining index weights for rural power network transformation and upgrading projects. Background technique [0002] The evaluation index system of the rural power grid transformation and upgrading project involves multiple levels such as power grid performance, enterprise benefits, and social impact, and each level is divided into several small indicators. There is incompatibility, so various indicators need to be standardized and dimensionless. In addition, the weight calculation methods of various indicators rely too much on human factors such as expert scoring to determine the weight of the indicators. It is difficult to unify the criteria for determining the weight of the indicators, and it is difficult to guarantee the scientificity and accuracy of the calculation results. Therefore, it is necessary to propose a standardized processing method and ind...
