Research on 'Supply and Demand Matching' Degree of taxi resources in 'Internet +' Age

摘要

In this paper, we will establish a Comprehensive evaluation model[1] of taxi resources, based on TOPSIS method. In the model, we consider several indexes: taxi no-load ratio. First, we analyzed the changing curve of each index in different time and space in Nanjing City. Then, the weight coefficient of each index is determined by entropy method. Finally, based on TOPSIS method, we got the changing curve of supply and demand matching relation in different area of Nanjing city. By analysing the changing curves, we draw a conclusion that most of the taxi resources are in the short supply degree, just in some travel peak gas may be in a state of oversupply.
