Group decision evaluation of high speed rail emergency plan based on index dictionary preference.

In order to scientifically and rationally evaluate the effect of high speed railway emergency plan during the emergency rescue, a framework of evaluation index system for high speed rail emergency plan was proposed. An emergency plan evaluation model based on the dictionary order preference of evaluation index of group expert was developed. Based on the evaluation results of single decision maker, the index preference of group experts can be calculated with the combination of evaluation index dictionary order preference of single decision maker using the method of majority rule. The results of example study showed that the evaluation method can effectively balance the differences among expert evaluation preferences and weaken the limitation of individual expert evaluation.
