摘要：
This paper analyzes the problem of raw material procurement under the price uncertainty. The scenario that the price of some kinds of materials vary with time unexpectedly and the materials have the stable consumption of demand at the same time is encountered constantly in practical material procurement. Meanwhile, in order to minimizing the cost of procurement, we need to make the decisions of when we should procure and how much materials we should buy with how much price we should pay under the condition of meeting demand. A general hypothesis in the most previous studies is that the price of procurement follows a certain distribution. However, price mostly cannot be clearly described in practical situations. Considering the material online procurement problem from online theory in this paper, a competitive strategy is proposed and we prove the ratio is better than the existed results. © 2016, Editorial Board of Journal of Systems Engineering Society of China.
