Program evaluation system and method based on analytic hierarchy process

Abstract

The invention provides a program evaluation system and method based on an analytic hierarchy process. The program evaluation system comprises an input unit used for inputting a to-be-evaluated program and evaluation indexes, a program evaluation hierarchical structure model establishment used for forming a multi-level analysis structure model according to the evaluation indexes, and correlation and membership relation between the indexes, a determination matrix establishment unit used for configuring a pairwise comparison matrix for factors on the same layer from the second layer of the hierarchical structure model until the lowermost layer, a single hierarchical arrangement obtaining unit used for calculating the single hierarchical arrangement from a determination matrix layer by layer and performing consistency detection, a hierarchical general ranking obtaining unit used for calculating a general ranking weight of each level for the system and performing consistency detection, and an obtaining unit used for obtaining a comprehensive evaluation value and program ranking of each program according to rating information and the hierarchical general ranking weight of each to-be-evaluated program. By adoption of the program evaluation system and method, the subjective decision of a decision maker can be fully reflected, scientific empowerment of the evaluation indexes is realized, and the program evaluation accuracy is improved.

Description

technical field [0001] The present invention relates to the field of radio and television, and more specifically, relates to a program evaluation system and method based on analytic hierarchy process. Background technique [0002] In the field of broadcasting and television, multiple indicators are usually used to evaluate users' preferences for programs, and the assignment of evaluation index weights is an important part of multi-objective decision-making. The weight of the index is the reflection of the different importance of the index in the evaluation process, and it is a comprehensive measure of the subjective evaluation and objective reflection of the relative importance of the index in the decision (or evaluation) problem. Whether the weight assignment is reasonable or not plays a vital role in the scientific rationality of the evaluation results; if the weight of a certain factor changes, it will affect the entire evaluation result. Therefore, the assignment of wei...

Its disadvantage is that it ignores the subjective preference information such as the subjective knowledge and experience of the decision maker, and sometimes the weight coefficient is unreasonable.
