A Fuzzy Rough Group Decision-making Model for Rating and Ranking IT Outsourcing Aggressive Risk

Risks are unavoidable in IT outsourcing (ITO), and it is critical to rank and rate the risk for the success of ITO, which is an important role in the competence of organizations.

The method can improve the fairness and efficiency of risk evaluation, and is verified by a case in a large-scale nuclear power station
