Evaluation of urban taxi-carpooling matching schemes based on entropy weight fuzzy matter-element

The evaluation of urban taxi-carpooling matching is the key index for the success of taxi carpooling. In this research, matter-element theory is introduced. Moreover, a matter-element evaluation model is established, and a matter-element evaluation algorithm based on fuzzy entropy weight is proposed. In accordance with the characteristics of the matching data, the algorithm takes the distance to the carpool destination, the distance to the carpool starting point, the carpool distance and the time to the carpool starting point in the passenger-matching scheme as the characteristic indexes of the evaluation category. A compound fuzzy matter-element matrix is established through an index fuzzy value method, and a matter-element matrix of a preferred membership degree and a fuzzy matter-element matrix of standard deviation are constructed. An index weight is determined through entropy weight method, and the closeness degree of the matter-element matrix is calculated. It avoids the shortcoming of traditional matter-element method which uses artificial determination of an eigenvalue index and correlation degree calculation. Experimental results show that the evaluation result of this algorithm is close to the actual evaluation result. In addition, the evaluation effect is better in this algorithm than in the traditional matter-element algorithm. (C) 2019 Elsevier B.V. All rights reserved.
