MODEL FOR NETWORK SECURITY SERVICE PROVIDER SELECTION WITH PROBABILISTIC UNCERTAIN LINGUISTIC TODIM METHOD BASED ON PROSPECT THEORY
针对企业选择网络安全服务提供商这一多属性群决策问题，提出一种融合前景理论和TODIM方法的概率不确定语言决策模型，并通过案例验证其有效性。
Choosing the optimal network security service provider (NSSP) is a very important part of enterprise management decision. And the choice of NSSP is a typical multiple attribute group decision making (MAGDM) issue. In order to provide a better decision method for MAGDM problems, this paper integrates the TODIM method and the probabilistic uncertainty linguistic term set (PULTS), so as to propose the probabilistic uncertain linguistic TODIM model based on the prospect theory (PT-PUL-TODIM). The model combines the advantages of the prospect theory and TODIM method. In the end, a case study concerning NSSP selection problem is given to demonstrate the merits of the developed methods.
