Problems solved by technology

[0004] ①: The status of distribution network equipment mostly adopts a multi-layer structure index system. When applying the joint analysis method to analyze its weight, the number of questionnaires based on the orthogonal test design is large, which makes the investigation difficult
[0005] ②: Due to the large number of questionnaires, there are sometimes logical contradictions when experts score
How to check and adjust the consistency of the questionnaire data, there is currently no good solution

Abstract

The invention provides a distribution network device status indicator weight analysis method based on conjoint analysis. The method includes the steps: 1, survey cards for a distribution network device status indicator are determined by an orthogonal test; 2, the survey cards are scored; 3, uniformity of scoring data is checked; 4, the scoring data with uniformity is fitted by a least square method, validity of the scoring data is checked so as to obtain distribution network device status indicator weight. Compared with the prior art, the method has the advantages that fewer survey cards are used without affecting implementation effect of the conjoint analysis, and the data of the survey cards are subjected to uniformity checking and adjustment.

Description

technical field [0001] The invention relates to a weight analysis method of a distribution network equipment state index, in particular to a distribution network equipment state index weight analysis method based on a joint analysis method. Background technique [0002] Conjoint analysis, also known as conjoint analysis, is a method of evaluating the needs and intentions of respondents and making decisions accordingly. When the traditional weight determination method is used to examine the importance of each attribute of a thing one by one, it is often impossible to give a very objective and precise answer; the joint analysis method, which is different from this synthetic analysis model, is decomposed, and can be investigated through the full profile preference survey. Statistical analysis of results that more closely reflects people's underlying measures. The basic idea is to simulate the choice of the respondents in the real situation after weighing the different states o...
