| Abstract: | The general context of e-mail market is analyzed.Differential equation is applied to construct the model of the increasing of e-mail users,which is used to predict the number of users of some mailbox in several years and the capacity of hard disk that should be provided.With the consideration of reducing cost,Ito stochastic process is applied,and the risk is evaluated,the model of dynamic hard disk supply is constructed to guide E-mail Company to arrange the appropriate capacity of the hard disk to meet the users'need and meanwhile reduce cost and risk to strengthen its competitiveness in the market. |

| Keywords: | hard disk capacity supply the average content degree of potential user stochastic differential equation Ito stochastic process risk degree |
