By extracting and summarizing the historical data, using Python language and analytic hierarchy process, coefficient of variation method, entropy method, the paper calculated the data, and finally accurately calculated the customer value and comprehensive ranking. The comprehensive evaluation of customer value implemented the transformation of railway freight marketing from single index evaluation to comprehensive evaluation.
