2、ad been presented. People make deeper and broader research in the area of the newsboy model as development over time. Most of research on inventory control focus on the complex restrictions a

3、nd transforms of mathematical model，without considering the situation that the value of inventory may add or depreciate. However, inventory value will increase or reduce in the real world. Firstl

4、y, the related literatures both at home and abroad about inventory models items are reviewed，and then the thesis analyses the status of research. Secondly, this thesis reviewed the traditional

5、news boy models including both interval and discrete scenarios. Because of approach in inventory control focus on the complex restrictions and transforms of mathematical model，without considering

6、the situation that the value of inventory may add or depreciate. In order to solve this problem, this thesis set up a single cycle economic order quantity model under the condition that the

7、 value changing of inventory will happen. In section three and section four , we describe uncertainty demand using two types of demand scenarios; namely interval and discrete scenarios. Accordin

8、g to the stochastic demand, the optimal order policy was given. This method suggested a new idea for inventory research and enlightened the way of this field. Based on the assumption of First

10、oof, with considering the stochastic demand, optimal order quantity and optimal expected profit. At last, the results were illustrated with numerical examples and sensitivity analysis was provided

11、 for related parameters. And then, by analyseing the setting models and the traditional news boy models including interval and discrete scenarios, the thesis show that the traditional models ar
