【摘要】：由于互聯(lián)網經濟迅猛發(fā)展的沖擊,對企業(yè)加快開展互聯(lián)網服務的要求也更加明顯。因此,為了提升在市場中的份額,企業(yè)也開始將電子商務業(yè)務轉向服務外包領域。企業(yè)通過電子商務外包(Electronic Commerce Outsourcing)不僅能夠實現(xiàn)自身利潤的最大化,而且有利于提升企業(yè)在行業(yè)中整體的競爭優(yōu)勢。電子商務外包承包商選擇決策理論研究并不廣泛,不僅涵蓋各類指標體系的建立,也涉及多個不同的定性和定量屬性,因而電子商務外包承包商選擇等管理決策問題也屬于一類多屬性決策問題。在現(xiàn)實的評價體系中,由于各方面因素的影響,單純的定性與定量信息的評價類型已經很難滿足實際決策問題的精確要求,往往需要采用定性與定量相融合的語言評價信息來對決策者的偏好進行描述。語言猶豫模糊集不僅可以表達決策者的定性偏好,而且可以反映出他們的不確定性和猶豫。因此,將語言猶豫模糊多屬性決策應用于企業(yè)電子商務外包承包商選擇問題中顯得尤為重要。本論文將語言猶豫模糊集與多準則妥協(xié)解法(Vlsekriterijumska Optimizacija I Kompromisno Resenje,簡稱VIKOR)相結合,充分考慮決策者的效用偏好,并且基于信息不完全理論,提出語言猶豫模糊VIKOR多屬性決策方法,解決電子商務外包承包商選擇等管理決策問題。以下是對本文的主要內容進行闡述。(1)基于語言猶豫模糊集的排序理論,考慮評價信息中語言術語集的個數(shù),定義了新的下標函數(shù),使其具有靈活的語義表達,更接近于實際的理論。其次定義了改進的得分函數(shù)和方差函數(shù),相比于過去的同類方法具有更強的區(qū)分度。(2)基于距離測度理論,提出語言猶豫模糊集的廣義距離測度,包括漢明(Hamming)距離測度,歐式(Euclidean)距離測度;廣義豪斯多夫(Hausdorff)距離測度,包括漢明豪斯多夫距離(Hamming-Hausdorff)測度,歐式豪斯多夫(Euclidean-Hausdorff)距離測度;混合廣義(hybrid generalized)距離測度,包括混合漢明(hybrid Hamming)距離,混合歐式(hybrid Euclidean)距離等。(3)本文提出了語言猶豫模糊VIKOR多屬性決策方法,基于信息不完全理論,分別構建(非)線性優(yōu)化模型,利用拉格朗日乘數(shù)法和最大偏差的方法來得到最優(yōu)屬性權重。(4)將方法應用在電子商務外包承包商選擇中,并對該方法的求解過程進行詳細討論。該方法適用于決策者所給的評價信息是不確定決策環(huán)境,這使得決策結果與現(xiàn)實生活問題更加一致,并且比同類方法更為客觀合理。
[Abstract]:Due to the impact of the rapid development of the Internet economy, the demand for enterprises to accelerate the development of Internet services is also more obvious. In order to improve their share in the market, enterprises have also begun to turn e-commerce services to the field of service outsourcing. Enterprises can not only achieve their own profits through Electronic Commerce Outsourcing. The maximization of the enterprise is beneficial to the promotion of the competitive advantage of the enterprise in the industry. The choice of decision theory of e-business outsourcing contractor is not widely studied. It not only covers the establishment of various index systems, but also involves many different qualitative and quantitative attributes. Therefore, the decision making problem of the contractor selection of the ecommerce outsourcing contractor is also a class of management decision. In the real evaluation system, in the actual evaluation system, because of the influence of various factors, the simple qualitative and quantitative information evaluation types have been difficult to meet the precise requirements of the actual decision problem. The qualitative and quantitative language evaluation information is often used to describe the preference of the decision-makers. It can not only express the qualitative preference of the decision-makers, but also reflect their uncertainty and hesitation. Therefore, it is particularly important to apply the language hesitation fuzzy multiple attribute decision to the choice of the outsourcing contractor of the enterprise. This paper is a language hesitant fuzzy set and multi criteria compromise solution (Vlsekriterijumska Optimizac). IJA I Kompromisno Resenje, referred to as VIKOR) combined, fully consider the utility preference of decision-makers, and based on incomplete information theory, the language hesitation fuzzy VIKOR multi attribute decision-making method is proposed to solve the problem of management decision of the contractor selection of e-commerce outsourcing. The following is the main content of this article. (1) hesitation based on language The ranking theory of fuzzy sets, considering the number of language terms in the evaluation information, defines a new subscript function, which makes it flexible semantic expression and is closer to the actual theory. Secondly, the improved score function and variance function are defined, compared with the same method of the past. (2) based on the distance measure theory, the theory of distance measurement is proposed. The generalized distance measure of language hesitant fuzzy sets, including the Hamming distance measure, the Euclidean distance measure, the generalized Hausdorf (Hausdorff) distance measure, the Hamming Hausdorf distance (Hamming-Hausdorff) measure, the Euclidean Moorhouse multiple (Euclidean-Hausdorff) distance measure, and the mixed generalized (hybrid generalized) distance. Measurement, including mixed Hamming (hybrid Hamming) distance, mixed Euclidean distance (hybrid Euclidean) distance, etc. (3) this paper proposes a language hesitant fuzzy VIKOR multi attribute decision-making method, based on incomplete information theory, constructs (non) linear optimization model respectively, and uses the Lagrange multiplier method and the maximum deviation method to obtain the optimal attribute weight. (4) The method is applied to the choice of the contractor in e-commerce outsourcing, and the process of solving the method is discussed in detail. This method applies to the decision maker's evaluation information is an uncertain decision environment, which makes the decision result more consistent with the real life problem, and is more objective and reasonable than the same method.
