【摘要】：隨著供應(yīng)鏈企業(yè)間的關(guān)系越來越緊密，企業(yè)間的信息共享顯得尤為重要，供應(yīng)鏈必須建立在信息共享上面，才能促進信息的流通。供應(yīng)鏈信息共享是指供應(yīng)鏈中的上下游各個企業(yè)相互共享自己的信息以期達到協(xié)調(diào)整個供應(yīng)鏈，實現(xiàn)整個供應(yīng)鏈效率最優(yōu)化。由于缺乏有效、可靠的量化評價模型,往往不容易確定供應(yīng)鏈信息共享程度。使得供應(yīng)鏈節(jié)點企業(yè)不能清楚認識自己所處的供應(yīng)鏈的真實運營狀況,在信息共享程度偏低時也很難意識到和采取有效的對策,從而導(dǎo)致供應(yīng)鏈整體運營成本升高和競爭能力下降,逐漸丟失市場優(yōu)勢。軟集合理論（Soft Set Theory）是一種新興的處理不確定問題的工具。它可以克服傳統(tǒng)傳統(tǒng)數(shù)學(xué)方法傳統(tǒng)數(shù)學(xué)方法概率論，模糊集理論，區(qū)間數(shù)學(xué)理論，粗糙理論處理不確定問題時參數(shù)化不合理的缺陷。軟集合描述對象的方法非常靈活。本文將軟集合理論應(yīng)用于供應(yīng)鏈信息共享評價的研究中，彌補了傳統(tǒng)的供應(yīng)鏈信息共享評價模型在考慮定量信息和定性信息的多種信息融合的情況下應(yīng)用的局限。本文的主要研究內(nèi)容和成果如下： 首先，本文在相關(guān)文獻的基礎(chǔ)上對供應(yīng)鏈信息共享評價和軟集合的研究現(xiàn)狀綜述，歸納總結(jié)出來幾種常用的供應(yīng)鏈信息共享評價模型的特點和不足，引入了軟集合的概念。第二，本文在供應(yīng)鏈信息共享評價指標體系構(gòu)建的原則下，歸納得到一套供應(yīng)鏈信息共享評價指標體系。第三，本文介紹了軟集合和雙射軟集合及雙射軟集合決策系統(tǒng)以及依賴度、重要度的相關(guān)定義，并且介紹了一種基于系統(tǒng)重要度的約減方法。第四，根據(jù)供應(yīng)鏈信息共享方案各指標對應(yīng)的實數(shù)值對8種供應(yīng)鏈信息共享方案進行了聚類分析，通過把定量信息轉(zhuǎn)化成了定性信息來構(gòu)造雙射軟集合，再通過計算雙射軟集合的參數(shù)約簡找出影響供應(yīng)鏈信息共享結(jié)果的關(guān)鍵因素，并且計算出了每個參數(shù)的重要度，把每個參數(shù)的重要性量化，得出了一種全新供應(yīng)鏈信息共享評價的新方法，豐富了現(xiàn)有的供應(yīng)鏈信息共享評價研究體系。
[Abstract]:With the increasingly close relationship between supply chain enterprises, the information sharing among enterprises is particularly important. Supply chain must be based on information sharing in order to promote the flow of information. Supply chain information sharing refers to the upstream and downstream enterprises share their own information with each other in order to coordinate the whole supply chain and realize the optimization of supply chain efficiency. Due to the lack of effective and reliable quantitative evaluation model, it is difficult to determine the degree of information sharing in supply chain. So that the supply chain node enterprises can not clearly understand the real operation of their supply chain, when the degree of information sharing is low, it is difficult to realize and take effective countermeasures. As a result, the overall operating cost and competitive power of the supply chain are increased and the market advantage is gradually lost. Soft set theory (Soft Set Theory) is a new tool for dealing with uncertain problems. It can overcome the defects of the traditional mathematical methods, such as probability theory, fuzzy set theory, interval mathematics theory and rough theory in dealing with uncertain problems. The method of describing objects by soft sets is very flexible. In this paper, the soft set theory is applied to the evaluation of supply chain information sharing, which makes up for the limitation of traditional evaluation model of supply chain information sharing under the condition of considering quantitative and qualitative information fusion. The main contents and achievements of this paper are as follows: firstly, this paper summarizes the research status of supply chain information sharing evaluation and soft set on the basis of relevant literature. The characteristics and shortcomings of several common evaluation models of supply chain information sharing are summarized and the concept of soft set is introduced. Secondly, based on the construction of supply chain information sharing evaluation index system, a set of supply chain information sharing evaluation index system is concluded. Thirdly, this paper introduces the decision system of soft set and bijective soft set and the definition of dependency and importance, and introduces a reduction method based on system importance. Fourthly, according to the real values of each index of the supply chain information sharing scheme, this paper makes cluster analysis of eight supply chain information sharing schemes, and constructs a bijective soft set by transforming quantitative information into qualitative information. Then the key factors that affect the result of information sharing in supply chain are found out by calculating the parameter reduction of double soft set, and the importance degree of each parameter is calculated, and the importance of each parameter is quantified. A new evaluation method of supply chain information sharing is obtained, which enriches the existing research system of supply chain information sharing evaluation.
