DEMATEL方法(决策试验与试验评估法)是一种运用图论与矩阵工具进行系统因素分析的方法。但此方法对系统因素间关系的评价仅限于实数域内,往往不适合描述现实生活中系统因素间复杂的影响关系。鉴于区间数能更有效地描述复杂的现象,本文将传统的DEMATEL方法拓展到了区间数领域,来弥补DEMATEL方法的这一不足。为此,本文建立了区间数初始直接影响矩阵,借助于区间数的运算法则和可能度排序,计算出区间数综合影响矩阵,并对系统因素进行分析,从而,提出区间数DEMATEL方法。然后采用区间数DEMATEL方法识别IT外包中知识转移影响因素,得到IT外包中知识转移过程中的原因影响因素、结果影响因素以及每个影响因素的重要程度,以此为IT外包人员给予相应的建议,同时也验证了该方法的实效性。
DEMATEL方法(決策試驗與試驗評估法)是一種運用圖論與矩陣工具進行繫統因素分析的方法。但此方法對繫統因素間關繫的評價僅限于實數域內,往往不適閤描述現實生活中繫統因素間複雜的影響關繫。鑒于區間數能更有效地描述複雜的現象,本文將傳統的DEMATEL方法拓展到瞭區間數領域,來瀰補DEMATEL方法的這一不足。為此,本文建立瞭區間數初始直接影響矩陣,藉助于區間數的運算法則和可能度排序,計算齣區間數綜閤影響矩陣,併對繫統因素進行分析,從而,提齣區間數DEMATEL方法。然後採用區間數DEMATEL方法識彆IT外包中知識轉移影響因素,得到IT外包中知識轉移過程中的原因影響因素、結果影響因素以及每箇影響因素的重要程度,以此為IT外包人員給予相應的建議,同時也驗證瞭該方法的實效性。

DEMATEL method ( Decision Making Trial and Evaluation Laboratory ) is a method for system factor analysis using graph theory and matrix tools .But the evaluation of the relationship between the system factors of this method is only limited to the real number field , not suitable for describing the complicated relationship between system factors in real life .Since interval number can more effectively describe the complex phenome-non, the traditional DEMATEL method is extended to interval number field ,making up for the shortcoming of DEMATEL method.First, this paper establishes the initial interval number direct influential matrix and then calculates comprehensive interval number influential matrix by arithmetic rules and possibility sequence of the interval number for analyzing the system factors , thus the interval DEMATEL method is put forward .Then this paper uses the interval DEMATEL method for identifying IT outsourcing influential factors , to find IT outsourcing reason influential factors、result influential factors and the important degrees of each influential factors .Based on this,corresponding suggestions for IT outsourcing personnel are given ,and at the same time the effectiveness of the method is verified .
