구매종속성이 존재하는 상황에서 부분 부재고 EOQ 모형에 대한 고찰

Purchase dependence is a frequent phenomenon in retail shops and is characterized by the purchase of certainitems together due to their unknown interior associations. Although this concept has been significantly examined inthe marketing field (e.g. market basket analysis), it has largely remained unaddressed in operations management. Since purchase dependence is an important factor in designing inventory replenishment policies, this paper demonstratesthe means of applying it to the partial backordering inventory model. Through computational analyses, this paper comparesthe performance of inventory models that either consider or ignore purchase dependence; the results demonstratethat inventory models that ignore purchase dependence incur more average cost per unit time than the model thatconsiders purchase dependence, and the impact of purchase dependence can increase in significance as the item setbecomes more closely correlated with regard to order demand.
