RFM模型+AI：银行客户分层运营实战代码

实战代码：基于 retail-marketing Skill | RFM分析 | 客户分层 | 精准营销

什么是RFM模型？

RFM是客户价值分析的经典模型：

• R (Recency)：最近一次交易时间
• F (Frequency)：交易频率
• M (Monetary)：交易金额

# RFM计算示例
from datetime import datetime

# 客户交易数据
customer = {
   
    "customer_id": "C10086",
    "last_trade_date": "2024-01-10",  # R: 5天前
    "trade_count_12m": 24,             # F: 年均24次
    "aum": 500000                      # M: 50万AUM
}

# RFM评分 (1-5分)
rfm = {
   
    "R": 4,  # 5天前 → 4分 (越近越高)
    "F": 5,  # 24次/年 → 5分 (越多越高)
    "M": 4   # 50万 → 4分 (越高越高)
}

# 客户类型: 重要价值客户 (R=4, F=5, M=4)
