[0040] like Figure 2 As shown, in one embodiment of the present invention, a comprehensive evaluation method for highway project quality engineering includes the following steps:

[0041] Step S1, combining theoretical research related to quality engineering and the characteristics of highway project construction, sorting and screening the key factors of highway project quality engineering, and constructing a three-layer evaluation index system including the criterion layer, the first-level index and the second-level index;

[0042] Step S2, creating key contents of the secondary indicator evaluation according to the secondary indicators and the characteristics of the highway project;

[0043] Step S3, for each indicator, based on the indicator weight value determined by the expert, the normalized weight value of the indicator is determined by AHP and the consistency of the weight matrix is ​​verified;

[0044] Step S4, statistically analyzing the scoring results of experts for each indicator and constructing a fuzzy membership matrix based on the membership function;

[0045] Step S5, performing comprehensive evaluation based on the comprehensive weight matrix and the fuzzy membership matrix.

[0046] The step S1 is specifically as follows: selecting the evaluation indicators of this study from six dimensions, namely, engineering design, engineering management, engineering quality, safety assurance, technological innovation and green environmental protection, and constructing a three-layer indicator system including a criterion layer, a primary indicator and a secondary indicator, as shown in Table 1:

[0047] Table 1: Three-layer indicator system including criteria layer, primary indicators and secondary indicators

[0048]

[0049]

[0050] In step S3, the key evaluation contents of each secondary indicator constructed are shown in Table 2.

[0051] Table 2, key evaluation contents of each secondary indicator

[0052]

[0053]

[0054]

[0055]

[0056]

[0057] The step S3 specifically includes: based on the indicator weight values ​​determined by the experts, determining the normalized weight values ​​of the indicators through the AHP hierarchy analysis method and verifying the consistency of the weight matrix.

[0058]

[0059] The aij in the matrix represents the ratio of the weight of indicator i to the importance of indicator j relative to the previous layer indicator, i, j = 1, 2, 3, ..., n; the aij should satisfy the following three relationships:

[0060] aij is the quantitative result of comparing the importance (fuzzy attributes) of each evaluation index by industry experts according to the 9-level scale method. The definition of the 1 to 9-level scale is shown in Table 2.

[0061] Table 3, Definition of the 1 to 9 scale

[0062]

[0063] We invited several experts to compare the importance of each evaluation index in the index system based on the needs of highway projects and quality engineering requirements, form a weight matrix, calculate the weight vector and perform consistency test. The results are as follows.

[0093]

[0094] The specific calculation process in the calculation result is as follows:

[0095] Normalize the weight matrix A to get the normalized weight value

[0096]

[0097] right Sum the rows to get At the same time Normalize and calculate the weight value Wi, and then use Wi to form the weight vector W.

[0098] in, W=(W1,W2,...,W n ) T ;

[0099] Calculate the maximum eigenvalue λmax of the weight matrix A, where

[0100] To ensure the consistency of the weight matrix, the eigenvalues ​​other than λmax should be close to 0, and the remaining n-1 eigenvalues ​​and absolute values ​​are taken as the index to check the consistency of the matrix and marked as CI. Generally, the larger the CI value, the greater the degree to which the weight matrix deviates from consistency, and vice versa.

[0101] The order n of the matrix will affect the consistency. Generally, the larger the n, the greater the subjective influence of the judgment. At this time, the consistency of the deviation is greater, and vice versa. In order to eliminate the subjective factor deviation caused by the order n to a certain extent, the average random consistency index is introduced, denoted as RI. The value of RI increases with the order of the weight matrix. The RI value is shown in Table 7.

[0102] Table 7. RI values

[0103]

[0104] The ratio of the consistency index CI to the average random consistency index RI of the same order of the matrix is ​​called the consistency ratio, denoted as The smaller the CR is, the better the consistency of the weight matrix is. It is generally believed that when CR < 0.1, the weight matrix meets the consistency standard, otherwise the weight matrix needs to be corrected.

[0105] According to the weight values ​​of evaluation indicators at different levels, the comprehensive weights of each indicator are obtained (Table 8). The comprehensive weight matrix of evaluation indicators for highway project quality engineering is constructed: A = [0.58%, 1.42%, 0.72%, 2.33%, 3.56%, 0.25%, 0.61%, 1.47%, 2.41%, 0.69%, 0.58%, 1.98%, 0.81%, 4.81%, 1.51%, 0.58%, 0.22%, 1.09%, 2.65%, 0.44%, 3.80%, 2.40%, 14.68%, 6.30%, 1.69%, 4.01 %, 0.56%, 1.06%, 2.99%, 1.45%, 0.77%, 0.28%, 0.87%, 2.64%, 2.64%, 9.76%, 3.75%, 1.43%, 1.50%, 0.40%, 0.95%, 0.31%, 0.74%, 0.12%, 0.10%, 0.10%, 0.29%, 1.56%, 0.60%, 1.37%, 0.27%, 0.87%, 0.48%, 0.09%, 0.42%, 0.04%]

[0106] The comprehensive weight calculation method is: represents the comprehensive weight, a i Indicates the weight of the corresponding criterion layer indicator, a j Indicates the corresponding first-level indicator weight, a k Indicates the corresponding secondary indicator weight.

[0108]

[0109]

[0110] The step S4 constructs a fuzzy membership matrix, and the specific processing flow is as follows:

[0111] Determine the evaluation index set of the object to be evaluated, B = {b1, b2, ..., b n};

[0112] Determine the evaluation set of the evaluation index, record the possible evaluation of a certain index as vi, and record the set of all possible evaluations as the evaluation set, represented by V, V = {v1, v2, ..., v n}, the possible evaluations are usually divided into five levels, this article adopts the five levels of "good, better, medium, poor, and bad";

[0113] According to the value of each indicator of the object to be evaluated, the fuzzy membership of the indicator is determined. First, m experts (m>10 in this evaluation method) are invited to judge which evaluation level each indicator belongs to based on the given evaluation set [good, better, medium, poor, poor], where the evaluation scores corresponding to the evaluation set are [5, 4, 3, 2, 1] respectively. Secondly, the expert evaluation results are counted, and the indicator evaluation results are converted into values ​​between [0, 1] through the corresponding membership function, where the membership function is expressed as follows:

[0114] Where Xij represents the evaluation level of indicator i made by the jth expert, m is the total number of experts, and Yi represents the normalized evaluation result value of indicator i.

[0115] According to the membership calculation method and expert evaluation results, the quantitative results of the quality engineering evaluation index of a highway project are shown in Table 9:

[0116] Table 9 Quantitative results of quality engineering evaluation indicators for a highway project

[0117]

[0118]

[0119] According to the quantitative results of the evaluation indicators shown in Table 9, the fuzzy membership matrix of the comprehensive evaluation indicators of the quality engineering of a highway project can be constructed as R = [0.80, 0.78, 0.82, 0.76, 0.73, 0.72, 0.69, 0.66, 0.73, 0.68, 0.76, 0.84, 0.86, 0.88, 0.82, 0.83, 0.86, 0.88, 0.89, 0.78, 0.86, 0.78, 0.81, 0. 86, 0.83, 0.84, 0.75, 0.80, 0.78, 0.82, 0.81, 0.78, 0.90, 0.91, 0.92, 0.75, 0.78, 0.73, 0.77, 0.75, 0.68, 0.67, 0.66, 0.75, 0.75, 0.80, 0.68, 0.80, 0.81, 0.73, 0.83, 0.75, 0.86, 0.65, 0.66, 0.64].

[0120] The step S5 is to perform a comprehensive evaluation based on the comprehensive weight matrix and the fuzzy membership matrix;

[0121] The comprehensive score of the quality engineering evaluation of a highway project can be obtained by the formula Q=A×R, where Q is the comprehensive score of the quality engineering evaluation of a highway project, A is the comprehensive weight matrix of the quality engineering evaluation indicators of a highway project, and R is the fuzzy membership matrix of the comprehensive evaluation indicators of the quality engineering of a highway project.

[0126] According to the comprehensive evaluation scores calculated in Table 10, the comprehensive evaluation result of the quality engineering of the highway project is 80.31 points.

[0127] In summary, the comprehensive evaluation method for highway project quality engineering provided by the present invention can provide technical support for scientific evaluation of the implementation of highway project quality engineering, and provide a decision-making analysis tool for the actual situation of highway project quality engineering implementation.
