According to the periodical character of customer relationship development (CRD) in Customer relationship management (CRM), in the paper the five-stage model of CRD is proposed. Based on the model, a Markov process model is established to analyze the dynamic development of customer relationship, through which the quantitative computation method of customer relationship lifecycle value (CRLV) is obtained. Based on the method, the influence of several factors in CRD on CRLV is analyzed quantitatively and some management strategies giving a reference to enterprises are obtained.
