An integrated inventory model with capacity constraint under order-size dependent trade credit, all-unit discount and partial backordering

In today’s competitive business situation, the supplier frequently offers his or her retailers a permissible delay period ( i.e. , trade credit) to stimulate sales. addition, capacity of any warehouse is limited in practice, thus retailer needs an additional rented (RW) store excess units when order quantity exceeds own (OW). Furthermore, with globalization marketing policy, may provide discounted price if purchase large enough. Considering all factors mentioned above, this paper we study integrated inventory model constraint under order-size dependent credit and all-units discount. Shortages are allowed partially backordered. unit production cost, which function rate, considered. An algorithm developed determine optimal replenishment policies for both retailer. Finally, numerical examples presented illustrate theoretical results. Sensitivity analysis major parameters performed some insights obtained.
