Efficiency evaluation index system weight calculation method

Abstract

The invention discloses an efficiency evaluation index system weight calculation method. The method comprises the steps of obtaining an efficiency evaluation index system hierarchical single sorting judgment matrix by utilizing a nine-indexing method; obtaining a projection vector of the hierarchical single sorting judgment matrix by using a principal component analysis method; and according to the projection vector and the hierarchical single sorting judgment matrix, determining a hierarchical total sorting weight of each layer of index relative to the highest layer of index. The invention discloses an efficiency evaluation index system weight calculation method. According to the method, a nine-indexing method is used for obtaining a hierarchical single-sorting judgment matrix, then a principal component analysis method is used for carrying out dimension reduction on the hierarchical single-sorting judgment matrix, and finally hierarchical total sorting calculation is carried out, sothat high-dimensional judgment data can be processed, the calculation principle is clear, the process is simple, and redundant features in the judgment matrix are effectively removed.

Description

technical field [0001] The application relates to a weight calculation method of an efficiency evaluation index system, which belongs to the technical field of efficiency evaluation. Background technique [0002] The analytic hierarchy process is a commonly used efficiency evaluation method. Its main idea is: according to the nature of the research object, the required goal is decomposed into multiple components, and according to the subordination relationship between the components, they are hierarchical to form a Hierarchical model. Based on the hierarchical structure model, the AHP organizes experts to score the indicators, performs single-level sorting and total-level sorting respectively, and finally obtains the importance weight of the lowest-level factors relative to the highest-level goals. [0003] The core of AHP is to construct the judgment matrix, and calculate the index weight vector according to the judgment matrix. Usually, the analytic hierarchy process com...
