Abstract: A method based on triangular fuzzy soft sets was proposed for risk evaluation problems with integrating fuzzy assessment information of different experts in traditional Failure Mode and Effects Analysis (FMEA).In the process of FMEA risk evaluation,different sets of risk evaluation were selected by each expert,and linguistic variable evaluation was used to integrate the evaluating information by "AND" operation in triangular fuzzy soft sets.The triangular fuzzy soft set of risk evaluation in failure modes and integrated weights of risk factors were obtained respectively.The comparison decision table of failure modes was calculated and the risk priority of failure modes was determined.A case of risk evaluation of manufacturing facility in mobile industry was studied to illustrate the effectiveness and reliability of the proposed method.
