Online Purchasing Strategy for Order- Based Procurement
摘要
Abstract
In the mode of purchase to order, purchase cost and delay cost are interactive.Vendors need to choose appropriate purchase strategy to balance the two items in order to minimize the total cost.The paper first analyzes the offline case where the total information on order demands is known beforehand, and gives an optimal offline strategy with time complexity.It then discusses the online purchasing strategy for the online case where order demands are unpredictable.A 2-comptitive online strategy is proposed, and a lower bound of competitive ratio for the online case is proved as well.关键词
