Language Hesitation Fuzzy VIKOR Method And Its Electronic Commerce Outsourcing Contractor Selection

Due to the rapid development of the Internet economy,the impact of enterprises to speed up the development of Internet services is also more obvious.Therefore,In order to increase the market share,companies also began to e-commerce business to the field of service outsourcing.Enterprises through e-commerce outsourcing not only to maximize their own profits,but also help to enhance the overall competitiveness of enterprises in the industry.E-commerce outsourcing can not only maximize enterprises' s profits,but also enhance the overall competitive advantage.How to choose the outsourcers is The key of enterprise e-commerce.At present,there is not much research on the choice of e-commerce outsourcing contractors,the selection of the index system is different,it involves a number of different qualitative and quantitative attributes.So the e-commerce outsourcing contractor choice and other management decision-making problem a class of multiple attribute decision making problems.At the same time,the quantitative type of evaluation form,such as real number,interval number,triangular fuzzy number,etc.,can not meet the requirements of accurate evaluation of the problem.In the actual evaluation,due to the complexity of objective things and the ambiguity of human thinking,the decision makers have given some hesitation ambiguities when comparing the merits and demerits of the two schemes.So it needs to use the qualitative language evaluation information to describe the preference.The language hesitation fuzzy set not only can express decision makers' qualitative preferences,but also can reflect their uncertainty and hesitancy.The language hesitation fuzzy sets are applied to the multi-attribute decision-making,taking into account the positional relationship of language membership.Therefore,the application of language hesitation fuzzy multiple attribute decision-making in enterprise e-commerce outsourcing contractor selection problem is important in theoretical and significance in practicals.This paper combines the language hesitation fuzzy set with the multi-attribute compromise solution(Vlsekriterijumska Optimizacija I Kompromisno Resenje,VIKOR),fully considers the utility preference of the decision maker,and puts forward the language hesitation fuzzy VIKOR multi-attribute decision-making method based on the information incomplete theory E-commerce outsourcing contractor selection and other management decision-making issues.The following is the main content of this article elaborated.(1)Based on the sorting theory of language hesitation fuzzy sets,considering the number of language terms in evaluation information,a new subscript function is defined which makes it more flexible in semantic representation and more closer to the actual theory.And we had defined a new score function and variance function,it has a big difference when comparing with the past similar method.(2)Based on the distance measure theory,the generalized distance measure of the language hesitation fuzzy set is proposed,including the Hamming distance measure,the Euclidean distance measure,the generalized Hausdorff distance measure,including the Hamming Hausdorff distance(Hamming-Hausdorff)measure,the Euclidean-Hausdorff distance measure,and the hybrid generalized distance measure,including the hybrid Hamming distance,the hybrid Euclidean distance,and so on.(3)In this paper,we propose a method of multi-attribute decision making of language hesitation fuzzy VIKOR.Based on incomplete information theory,we establish the(non)linear optimization model,and use the Lagrangian multiplier method and the maximum deviation method to obtain the optimal attribute Weights.(4)The method is applied to choose the e-commerce outsourcing contractor,and the process of solving the method discussed in detail.This method is applicable to the decision information given by the decision maker.The decision result is consistent with the real life problem and is more objective and reasonable than the similar method.
