The hybrid CoCoSo decision making model with interval value Neutrosophic set for evaluation the digital maturity of fimrs: Evidence from Vietnam

Assessing the digital maturity of businesses plays a crucial role in their development in the digital environment. Neutrosophic sets have been widely applied in many problems to address uncertainty in complex realities. The Combined Compromise Solution (CoCoSo) techniques have been used to address multi-criteria decision making problem. In this paper, an hybrid model combining the CoCoSo technique, entropy, and score function is used to address multi-criteria decision making problem under interval Neutrosophic environment. Information entropy is used to manage the weighted values of criteria in the decision-making model, and the score function is used to transform the evaluation into interval value Neutrosophic in the CoCoSo technique. Finally, the digital maturity level of a business is evaluated using proposed integrated model.
