An Empirical Study on Fuzzy Comprehensive Evaluation of Red Tourism Resources Based on AHP

Red tourism, which is featured with spiritual culture, resource fusion and historical socialization, is a remarkable innovation with Chinese characteristics. It is the shinning point of China’s tourism business development. This paper will show the objective and correct evaluation of red tourism resource. Firstly, it will create evaluation index system by theoretical analysis method and expert consultation method. Secondly, it will evaluate each object synthetically by fuzzy comprehensive evaluation method and analytic hierarchy process. Finally, through case study of General Zhang Aiping’s, Former Residence in Dazhou, Sichuan Province, conclusion and related suggestion will be achieved.


Introduction
Red tourism is one of the most significant features in China's old revolutionary base areas.Except carrying forward revolutionary spirit and culture, also it could bring considerable economical benefits for tourism region, which is one of the methods to improve old revolutionary base areas' culture and economy.In recent years, although red tourism had been developing boomingly, there still are several problems and shortages during the development, such as: the inadequacy in understanding importance of red tourism, the neglect in economical benefit brought by red tourism, the lagging in propagates of red tourism and so on.Until now, scholars had done lots of research work regarding the development of red tourism [1]- [8].This paper will evaluate each object synthetically by fuzzy comprehensive evaluation method and analytic hierarchy process.And through case study of General Zhang Aiping's, Former Residence in Dazhou, Sichuan Province, conclusion and related suggestion will be achieved.

Comprehensive Evaluation Index System for Red Tourism Resource
The establishment of comprehensive evaluation index system for tourism resource should follow the rules of scientificalness, hierarchy, integrality, operability and comparability [1].In this paper, we combine theoretical analysis method, expert consultation method and other related factors; comprehensive evaluation index system for red tourism resource is shown in Table 1.

Model of Fuzzy Comprehensive Evaluation
The basic idea of the fuzzy comprehensive evaluation method is to follow the step of "qualitative-quantitative-qualitative", which is start with qualitative research, and quantitative processing, and then obtains qualitative evaluation result [1].The concrete model factors including the followings [4]: 2) Evaluate fuzzy evaluation matrix , here, ij r represents the membership degree of factor i U to comment j V .

Using Analytic Hierarchy Process (AHP) to Calculate Weight
It is a very important step to determine the weight of evaluation index in fuzzy comprehensive evaluation model, and there are many methods to do it, such as w is the weight of criterion i, and j w is the weight of criterion j.
2) Compute the weight vector.Using MATLAB to calculate the maximum eigenvalue λ of matrix A and its corresponding characteristic vector (which is normalized), the vector is weight vector which represents the weight of each 3) Check the consistency of the pair-wise comparison matrixes through calculating the consistency index CI and consistency ratio CR.The formula is , 1 where n is the order of matrix A, and RI is the average random consistency index for matrices of order n, calculated as follows: When CR is greater than 0.1, λ is not satisfied, and inconsistent judgments must be readjusted in order to improve the consistency.
4) Compute the combination weight vector.If the sequencing weight vector of the (k − 1)th layer factor towards the total goal is The entire factors of the kth layer towards the synthetic sequence vector of the total goal are given by the following equation: where ( ) k P is the sequencing weight vector of the kth layer factor towards the (k − 1) the layer factor.

Case Study
This next will take the Zhang Aiping's former residence in Da Zhou as an example, using the fuzzy comprehensive evaluation model, which use the analytic hierarchy process to calculate weight, to evaluate the red tourism resources of Zhang Aiping's former residence.Specific steps are as follows.

Data Source
According to the red tourism resources evaluation index system, the main content of the research questionnaire is the satisfaction degree of the visitors to the evaluation index, and the grade option is set to be very satisfied, satisfied, gener-

Determine the Index Weight
According to the expert investigation method, the pair-wise comparison matrixes are established as follows: The weight of each index as shown in Table 3.

Fuzzy Comprehensive Evaluation
The evaluation objects are 1 2 3 , , B B B , evaluation Indexes are 1 2 9 , , , U U U  , and comment set V contents very satisfied, satisfied, general, dissatisfied, and very dissatisfied.Let the membership degree ij r be the ratio of the number of factor i U to comment j V to the total number of people participating in the survey, then the fuzzy evaluation matrixes can be structured as follows:  The fuzzy evaluation result contains two parts: the target hierarchy and the rule hierarchy.The fuzzy sets of three rule hierarchy are calculated as follows: , 1, 2, 3 And it can be calculated: ( ) , the fuzzy sets of target hierarchy can be calculated as: ( ) * 0.1549, 0.3526, 0.3114, 0.1119, 0.0691 C WR = = .Finally, according to the Li Kete's five scales, the five comments are evaluated as Table 4: Then the evaluation results are calculated: It is shown in Table 5.

Result Analysis and Suggestion
Based on the evaluation result, the comprehensive evaluation value E for Zhang Aiping's, Former Residence, red tourism resource is 3.4123.According to evaluation standard, this red tourism resource is above average, which means that the development of it is reasonable and positive although some spaces for development and improvement exist.
The evaluation value for resource value, scale of scenic spot and auxiliary business are 1 2 3 3.5449, 3.4305, 3.1380 respectively.Resource value (E 1 ) is the best, which shows that it is the most obvious worth and contribution to comprehensive evaluation of this red scenic spot.According to the portion of four evaluation indexes, revolutionary historical culture value takes significant part.As the glorious history of General Zhang Aiping, it indicates that this red scenic spot contains rich revolutionary historical culture connotation, which has affected later generations positively too much.Evaluation value of scale of scenic spot is better than comprehensive evaluation value, which means that this spot in U .4) Build the fuzzy comprehensive evaluation model C W R = ⋅ , and get the fuzzy evaluation result of all factors in U set.

Comprehensive evaluation results of red tourism resources.possesses preferable capacity for visitors.Actually, it covers an area of around 500 Mu to be able to bear more than 10 thousand tourists' visiting at the same time.Tourism auxiliary business is the worse, which is lower than comprehensive evaluation value to bring negative effect for comprehensive evaluation.So auxiliary business needs to be developed and improved dedicatedly by related parties.Among traffic, catering and tourism goods, catering takes the highest portion and traffic takes the lowest portion.It indicates that traffic of this spot is relatively good, but catering and tourism good is poor, which should be improved as soon as possible.
