Consumer evaluation method and device based on RFM model, and medium

The invention provides a consumer evaluation method and device based on an RFM model and a medium, and the method comprises the steps: extracting customer consumption data from a customer database, carrying out the data classification of the customer consumption data according to different geographic regions, carrying out the vectorization processing of a customer consumption data set after the data classification, obtaining a customer set X = {x1, x2,... xi,... xn}, 1 < = i < = n, n is the number of customers; according to the customer consumption data after data classification, calculating a time interval R index of last consumption of each customer, a consumption frequency F index of a specified time period and a total consumption amount M index of the specified time period; and calculating the weight coefficients of the indexes R, F and M as [mu] r, [mu] f and [mu] m by adopting an analytic hierarchy process, determining a weighted calculation formula of the comprehensive value of each customer, and calcu
