ABSTRACT

This paper establishes an objective evaluation algorithm for roller coaster ranking the data of roller coaster is first cleaned and normalized. Five evaluation indicators were selected by consumption level. The combination weighting method of combining the entropy method and the coefficient of variation method is used to determine the weight of the indicators. The combined weights of the indicators are obtained: W = (0.2873, 0.4702, 0.1866, and 0.056). A comprehensive evaluation model of the improved rank-sum ratio method and the TOPSIS method based on Mahalanobis distance was established, and the roller coaster was comprehensively evaluated.
