Abstract

As part of their marketing policy, some suppliers allow retailers a period of credit in anticipation of increasing demand for the products they supply. The opportunity to defer payments on products through credit transactions has the effect of reducing retailers' inventory investment costs, and as a result, retailers determine selling prices in anticipation of increased demand from buyers. This study aims to analyze the inventory model that determines the retailer's selling price and EOQ(Economic Order Quantity) under the assumption that the buyer's demand is an exponentially decreasing function of the retailer's selling price in the credit transaction supply chain consisting of suppliers, retailers, and buyers. The products supplied for problem analysis include the case of deteriorating products that deteriorate over time, and the effect of the credit transaction period, the index of price elasticity and the degree of deterioration on the retailer's selling price and EOQ is analyzed.

마케팅 정책의 하나로 일부 공급자는 소매상에게 공급하는 제품에 대한 수요 증대를 기대하면서 일정 기간의 신용 거래를 허용한다. 신용 거래에 의한 제품 대금에 대한 지불 유예의 기회는 소매상의 재고 투자 비용을 절감시키는 효과를 가져 오게 되고, 결과적으로 구매자의 수요 증대를 기대하면서 소매상의 판매 가격을 결정 하게 된다. 본 연구는 공급자, 소매상 그리고 구매자로 구성되는 신용 거래 공급망에서 구매자의 수요가 소매상의 판매 가격에 지수적으로 감소하는 함수라는 가정 하에 소매상의 판매가격과 주문 로트 크기(EOQ: Economic Order Quantity)를 결정하는 재고 모형을 분석하고자 한다. 문제 분석을 위하여 공급하는 제품은 시간의 경과에 따라 변질되는 퇴화성 제품의 경우를 포함하고, 신용 거래 기간과 가격탄력지수 그리고 퇴화의 정도가 소매상의 판매 가격과 주문 로트 크기에 미치는 영향을 분석 해 보고자 한다.
