The Evaluation Model of Unascertained Measure on Operation Quality of Transit Equipment
As one of typical multilevel fuzzy comprehensive evaluation, the key step for the evaluation of operation quality of urban taxi transportation system is to converse a series of membership degrees from membership degrees of bottom indexes. However, the existing converse algorithms of membership degrees are questionable because of redundant data of membership degrees of indexes, which are useless to objective classification, are involved in calculation of it of the objectives. Therefore, in order to classify the objects properly, a filtering algorithm, which can filter redundant data firstly in membership degrees of indexes that are useless for objective classification, is proposed to extract the valid values to converse membership degrees. Without the redundant data, a general algorithm for conversing membership degrees is given to evaluate the operation quality of urban taxi transportation system.
