Problems solved by technology

When the results cannot pass the consistency test and the survey results must be corrected, many scholars have conducted research on the consistency improvement method of the judgment matrix. Generally, mathematical transformation is used to convert the judgment matrix into a consistency matrix, but this is not considered in the improved model. Maintaining the original judgment information of the decision maker, and for the adjustment of the judgment matrix, it is very important to maintain the original judgment information of the decision maker, otherwise the improvement plan may not reflect the real preference of the decision maker, resulting in a result that is inconsistent with the actual situation

Embodiment example

[0074] Taking the expressway in Liaoning Province as an example, the weight analysis of the expressway pavement performance index PQI sub-items PCI, RQI, RDI and SRI is carried out. The design expert survey form is shown in Table 1.

[0075] Table 1 Expert Survey Form

[0076]

[0077] 20 experts from technical and management units of the expressway industry conducted an overall ranking of the importance of the four indicators of PCI, RQI, RDI and SRI, and collected the overall ranking results of the importance of the 20 experts.

[0078] Design three importance parameters of equal importance, slightly important, and obviously important, and collect the results of 20 experts comparing the importance of adjacent indicators after overall ranking of importance according to the importance parameters.

[0079] Table 2 lists the results of comparing the importance of adjacent indicators of an expert:

[0080]

[0081] According to the result of the comparison of the importan...

Abstract

According to the pavement use performance weight analysis method based on the modified analytic hierarchy process, firstly, all single items are subjected to importance degree overall sorting, the importance degrees of adjacent indexes are compared in sequence, then a judgment matrix is constructed, the judgment matrix of all the indexes is calculated, and the weights of all the single items of indexes are obtained. The judgment matrixes obtained through the improved analytic hierarchy process are all consistency matrixes, and the situation that consistency inspection is not passed is avoided.The result shows that the importance degree of each single index in experts in different technical fields is comprehensively evaluated by analyzing the weight of the pavement use performance index byadopting an improved analysis hierarchy analysis method, and the obtained weight result is more accurate, comprehensive and reliable, and more conforms to the actual situation of the weight of the analyzed local pavement use performance index.

Description

technical field [0001] The invention belongs to the field of expressway pavement performance index weight analysis, and relates to a pavement performance index weight analysis method based on improved analytic hierarchy process. Background technique [0002] In the current research on the weight of expressway pavement performance index, it is complicated and professional to determine the weight of each sub-index in PQI. The traffic volume of different regions and different routes, the pavement structure and climate are different, and the pavement performance index is reflected in the great difference. The weight coefficient should reflect the local disease characteristics and the overall understanding level of the road industry. [0003] Analytic Hierarchy Process (AHP for short) is a decision analysis method that combines qualitative and quantitative analysis. It has the characteristics of applicability, simplicity, practicability and systematization. It is an effective t...
