Abstract: A safety risk management evaluation index system of maintenance engineering management outsourcing contractors is established based on analysis of related regulations and manuals, expert interview, questionnaire and other methods. The corresponding evaluation model is also established. Combinated weighting method employing AHP and entropy weight method is adopted, correlation degree among safety risk management evaluation indices of contractors is calculated, and the safety risk management levels of contractors are obtained.Finally, model verification is carried out. Result shows that the index system and evaluation model are suitable for evaluating safety risk management of contractors, providing reference for engineering operation.

Key words: maintenance engineering management outsourcing, contractors, safety risk, improved matter-element extension model
