example

[0044]Example: Assume that 8 quality characteristics of ISO / IEC25010 are selected as the evaluation indicators of software quality (functionality, reliability, effectiveness, operability, security, Compatibility, maintainability and portability), ask experts to compare the importance of 8 indicators in software quality, and the comparison level is divided into 9 levels from low to high (absolutely Unimportant, very unimportant, basically unimportant, slightly unimportant, equally important, slightly important\basically important, very important, absolutely important), and calculate the weight of each indicator according to the expert scoring results.

[0045] The specific process of the indicator weight evaluation method based on expert interval scoring proposed by the present invention is as follows: figure 1 As shown, the method may include the following steps (step S101-step S107).

Abstract

The invention aims to a multi-objective decision problem, provides an index weight assessment method based on section rating of experts, and mainly solves the problem of consistency in index weight assessment of the experts. The method comprises the following steps: when comprising rating on two indexes is performed, the experts are not required to give a determined judgment result, while the judgment result can be represented by a discrete section containing one or more than one judgment result; an iterative search algorithm is designed to search a pairwise index comparison matrix which has the optimal consistency in section rating results of the experts; according to the optimal-consistency matrix, a logarithm least square method is utilized to calculate weights of each indexes. According to the invention, the section rating is used to replace the determined rating, on one hand, the rating difficulty of the experts is reduced, and on the other hand, the inconsistency of rating results can be effectively improved.

Description

technical field [0001] The invention relates to the field of multi-objective decision-making or information fusion, in particular to a method for evaluating index weights. Background technique [0002] In the fields of multi-objective decision-making and information fusion, the importance evaluation and weight calculation between different indicators and attributes are common problems. In the traditional indicator weight evaluation, experts compare and score different indicators in pairs, generate a pairwise comparison matrix of indicators, and use the log least squares method to calculate the weight of each indicator. [0003] Experts compare the importance of indicators based on their own experience and professional knowledge, but due to the limitations of experience and professional knowledge and the complexity of decision-making issues, experts are often difficult to make deterministic judgments about the importance of indicators. However, in the traditional index weigh...
