Customer Classification Method in theMetrological Industry Based on the PRFMModel

However, this approach lacks the necessary granularity for effective classification. Recognizing the significance of calibration period duration in assessing customer value within this industry, this study introduces the variable 'Period' to augment the traditional Recency Frequency Monetary model, yielding the Period Recency Frequency Monetary model.

This model facilitates more accurate evaluation of customer value and categorization within the metrological industry. Empirical testing validates the efficacy of this method, which not only aligns with industry requirements but also extracts valuable insights from customer data, thus laying the groundwork for personalized service provision.
