In this paper, we discuss the product selection problem of the information security technology system under the conditions of existing cooperation between the security products. We introduce the conception of cooperative performance-price ratio of such products in the system and establish a corresponding mathematical model. For this problem, we designed a(More)
In order to improve the accuracy of the wind speed forecasting in the wind farm, this paper presents an ARIMA-ARCH model, which considers the heteroscedastic effect between the fluctuation of wind speed and the characteristics of the change of wind speed, to forecast the wind speed. First of aU, the ARIMA model for the wind speed time series is built by(More)
The grounding grid is commonly installed in the substation. When itpsilas damaged, restoring and improving work not only affects the production, but also it is difficult to carry it out. In this paper, by using integrated translation and iterative method, we establish a new optimization model of quadratic programming with constraints. By solving the model,(More)

In this paper, we discuss the product selection problem of the information security projects under the conditions of existing cooperatively in the security products. We introduce the conception of system cooperative safety coefficient, establish the multi-objective optimization model which maximize the total coordination performance-price ratio, the total(More)
