The 2‐tuple linguistic neutrosophic set (2TLNS) does a good job in coping with vague and uncertain environments and has been widely used in numerous fields. In this article, we come up with a new solution of multiple attribute group decision‐making (MAGDM) problems, named as the modified TODIM method based on cumulative prospect theory and 2‐tuple linguistic neutrosophic sets (CPT‐2TLN‐TODIM method). To ensure relatively objective attribute weights, the CRITIC is integrated into this new model in this paper. The CPT‐2TLN‐TODIM method fully considers the psychological state of decision makers that makes it more realistic. What's more, we introduce the application of CPT‐2TLN‐TODIM method in the evaluation of network security assessment team for verifying the practicability of the CPT‐2TLN‐TODIM method. And finally, the reliability of CPT‐2TLN‐TODIM method is confirmed by comparing with other existed methods. In the immediate future, we will further explore the application of this method in other fields and keep trying to put forward more scientific and reasonable methods to solve MAGDM problems.

基于带有二元语言中智集的累积前景理论的多属性群决策的TODIM方法

2元组语言中智集（2TLNS）在应付模糊和不确定的环境方面做得很好，并且已广泛用于许多领域。在本文中，我们提出了一种多属性组决策（MAGDM）问题的新解决方案，称为基于累积前景理论和2元语言中智集的改进TODIM方法（CPT-2TLN-TODIM方法）。为了确保相对客观的属性权重，本文将CRITIC集成到此新模型中。CPT-2TLN-TODIM方法充分考虑了决策者的心理状态，使其更加现实。此外，我们介绍了CPT-2TLN-TODIM方法在网络安全评估团队评估中的应用，以验证CPT-2TLN-TODIM方法的实用性。最后，通过与其他现有方法进行比较，可以确定CPT-2TLN-TODIM方法的可靠性。在不久的将来，我们将进一步探索该方法在其他领域的应用，并继续尝试提出更科学合理的方法来解决MAGDM问题。
