摘要: To reduce inventory and increase sales, the supplier frequently offers retailer a permissible delay in payments if orders more than or equal to predetermined quantity. In 2012, Liao et al. proposed an economic order quantity model for with two warehouses when linked this paper, we attempt overcome some shortcomings of their mathematical model. Then, apply existing theoretical results fractional convex programs prove that annual total variable cost is pseudoconvex. Hence, optimal solution exists uniquely, which simplifies search global minimum local solution. Finally, run couple numerical examples illustrate problem compare solutions between theirs ours.
