基于区间数的拓展 DEMATEL 方法及其应用研究
Theory and Application Study on Extended DEMATEL Method Based on Interval Number
摘要
Abstract
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 .关键词
