Abstract

The purpose of this study is to specify a probabilistic tracking mechanism for customer luxury purchase implemented by hidden Markov model, Bayesian inference, customer satisfaction and net promoter score. In this paper, we have designed a probabilistic model based on customer's actual data containing purchase or non-purchase states by tracking the SPC chain : customer satisfaction -> customer referral -> purchase/non-purchase. By applying hidden Markov model and Viterbi algorithm to marketing theory, we have developed the statistical model related to probability theories and have found the best purchase pattern scenario from customer's purchase records.

마케팅 분야에서는 제품품질, 고객만족, 고객추천을 바탕으로 구매행동과의 영향 유무 및 상관관계를 통계적 Regression 방법으로 가설 검증하는 것을 주요한 연구 대상으로 하고 있다. 또한 최근에는 ASCI와 같은 고객만족지수 혹은 라이켈트의 NPS와 같은 고객추천지수를 바탕으로 실제 기업성과와 연관되는 시장 지분에 어떠한 영향을 미치는 지에 대한 통계적 분석 연구도 활발히 이루어지고 있다. 본 연구에서는 실제 고객이 매장을 방문하여, 과거 고객카드에 명품을 구매하던 구매하지 않던 간에 만족/불만족을 표시한 체인 및 고객 추천의향을 검토하여 Hidden Markov Model을 이용한 고객의 최상의 구매패턴을 분석하는 확률적 기법에 대하여 연구하는 것을 목적으로 하고 있다. 이를 바탕으로 고객만족 -> 고객추천의향 -> 고객추천행동->구매 및 재구매 체인에 대응하는 실제 소비자의 구매패턴을 고객만족과 NPS(순추천지수) 및 여러 수리통계적 이론-Hidden Markov Model, Bayesian Inference, Maximum Likelihood Estimation을 이용하여 확률적 추적 메카니즘을 구현하는 것을 목표로 한다. 제시된 목표는 인공지능을 구현하는 이론과 알고리듬을 사용하여 달성되었기에 이론적 추적 메카니즘을 여러 인공지능망 -DNN, CNN, GAN등을 사용하여 기업에서 사용할 수 있는 고객의 구매패턴 앱으로 발전시키는 것을 후속연구에서 기대한다.
