step S40, determining the weight and fuzzy matrix of each level of evaluation factors;
and step S50, comprehensively evaluating the safety service quality of the passenger transport cableway according to the obtained fuzzy matrix and the combination of the safety service quality evaluation level set.
The comprehensive evaluation method for the safety service quality of the passenger transport cableway, disclosed by the invention, is characterized in that the influence factors of the safety service quality of the passenger transport cableway are summarized and summarized through index sea election and questionnaire survey, and a passenger transport cableway safety service evaluation index system is established; according to the established index system, a corresponding factor set and a weight set can be established; establishing a safety service quality grade by referring to relevant regulation standards; determining the weight of each level of evaluation index by expert synthesis and an analytic hierarchy process; and comprehensively evaluating the safety service quality of the passenger ropeway by combining the service quality grade according to the index weight and the expert mark. The method constructs a two-layer evaluation system, and quantitatively evaluates the safety service quality by combining an analytic hierarchy process, so that the safety of the cableway is improved.
Step S10 specifically includes: the influencing factors of the safety service quality of the passenger ropeway comprise the regulation standard, the emergency plan, the fire control responsibility, the security order and the safety prompt.
In the specific implementation process, taking a certain passenger ropeway in Hangzhou as an example, through field research, index sea selection and the like, the influence factors influencing the safety service quality of the passenger ropeway are summarized into 5 aspects: regulatory standards, emergency plans, fire responsibilities, security order, and safety tips.
In fig. 2, the target layer is passenger transport cableway safety service quality evaluation (a), and the intermediate layer (B) has 5 factors which are respectively a regulation standard, an emergency plan, fire fighting responsibility, a public security order and a safety prompt; the bottom layer (C) has 16 factors, namely timely updating of the system according to the regulations (C1), implementation of the organization of the regulations (C2), regular inspection of related equipment (C3), establishment of heating of emergency plans (C4), establishment of emergency rescue organization (C5), preparation of rescue equipment and rescue goods (C6), organization emergency exercise (C7), integrity of fire-fighting facilities (C8), smoothness of safety channels (C9), fire-fighting training of workers (C10), peak operation support mechanism (C11), inhibition of public order lines (C12), planning of work service areas (C13), setting of warning signs (C14), establishment of riding notice boards (C15) and safety needs before riding (C16).

The pairwise comparison of two evaluation indexes is usually represented by a nine-scale method, 1,2,3 … 9 and the reciprocal thereof, wherein 1,3,5,7 and 9 respectively represent that the i factor is equally important, slightly important, relatively important, very important and absolutely important than the j factor. 2,4,6,8 indicates that the i factor is between 1,3,5,7,9 more important than the j factor. The calculation result of the index weight of each layer is as follows: the weight matrix of the B level to the A level is P, and the weight matrix of the C level to the B level is P1, P2, P3, P4 and P5 respectively.
And step S30, grading the safety service quality of the passenger transport cableway according to the related legal regulations and expert opinions of the passenger transport cableway to obtain an evaluation grade set.
In the specific implementation process, according to the passenger transport cableway safety service specification and the on-site interview investigation, the passenger transport cableway safety service quality is divided into 5 grades Q ═ poor, medium, good, excellent and super-excellent }, and after a comment set is established, the safety service of the passenger transport cableway can be comprehensively characterized according to the membership degree.
Step S40, obtaining a weight value by pairwise comparison of evaluation indexes at all levels as follows:
P＝[B1,B2,B3,B4,B5]＝[0.0359,0.0799,0.4706,0.2687,0.1449]
P1＝[C1,C2,C3]＝[0.0675,0.1991,0.7334]
P2＝[C4,C5,C6,C7]＝[0.0441,0.1015,0.2887,0.5658]
P3＝[C8,C9,C10]＝[0.7334,0.1991,0.0675]
P4＝[C11,C12,C13]＝[0.7429,0.1939,0.0633]
P5＝[C14,C15,C16]＝[0.1662,0.0726,0.7612]
and respectively carrying out consistency check on the judgment matrixes, wherein the ratio of a consistency index CI (consistency index) to a random consistency index RI (random index) of the check result is less than 0.1, so that the obtained judgment matrixes have consistency, and the weight of each index has reliability.
According to the results of the on-site investigation, experts related to the field of the cableway and special equipment are invited to comprehensively score the evaluation cableway, and the specific scoring results (as shown in table 3) are as follows:
TABLE 3
According to the expert scoring and the obtained index weight of each layer, each fuzzy evaluation matrix can be calculated as follows:
in summary, the secondary index factors B1, B2, B3, B4, and B5 are comprehensively evaluated according to the weight sets of the evaluation factors and the evaluation matrix, and the evaluation matrix is as follows:
then the evaluation matrix of the B level to the target level A is:
and step S50, comprehensively evaluating the safety service quality of the passenger ropeway according to the evaluation grade set.
In a specific implementation process, the comprehensive evaluation matrix R and the weight set P of the a-level evaluation factors are substituted into a comprehensive evaluation formula S ═ R × P to be calculated:
according to the comprehensive evaluation result, the maximum value in the S is 0.4673 by combining the maximum membership rule, and the corresponding evaluation grade set of the value in the evaluation result is 'excellent', namely the comprehensive evaluation result of the safety service quality of the passenger ropeway is excellent and the safety service quality is excellent.
