Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
In this paper, we consider the inventory problem in which decisions on purchasing time and quantity should be made by an online player without knowledge of future price of finished goods. The problem is studied from the perspective of competitive analysis. The competitive ratio of an online strategy relative to a given input instance is the ratio of the strategy´s performance to the offline optimal. Under the online algorithm approach, we formulate two models and dprice-threat-based algorithm is established. Following that, numerical examples concerning competitive analysis for the algorithms are given. Finally, some future research directions are pointed out.
