A Variable Precision Fuzzy Rough Group Decision- making Model for IT Outsourcing Risk Evaluation in Nuclear Power Industry

摘要

Risks evaluation is critical for the success of IT outsourcing. It is especially important in nuclear industry due to high concerns about safety and service quality. This paper proposes a new integrated methodology, Variable Precision Fuzzy Rough Group Decision-making (VPFRGDM), to evaluate the risk in IT outsourcing. This method can improve fairness, flexibility and efficiency of risk evaluation, and is verified by a case in a large-scale nuclear power station.
