The quality and yield of products in the process of aluminum hot rolling is affected seriously by the load distribution. The load distribution of the hot tandem rolling is actually a problem of multi-objective optimization(MOO. The model of the rolling schedule was established based on slippage factor, which was also set as an optimization objective. In this paper, an improved NSGA-II is applied to optimize the rolling schedule of aluminum hot tandem rolling. This paper also proposed a method to select the best solution based on the preference after process of the improved NSGA-II. This method shows its ability on the slippage preventing and load distribution.

This paper presents a symmetric cooperation strategy for cooperative relay networks with multiple users. The multi-user symmetric cooperation model and the relay selection algorithm are proposed. Then, the time slot allocation problem is cast into a bargaining problem, and the optimal time slot allocation solution is obtained by Nash bargaining solution (NBS). Moreover, we also consider the implementations of the cooperation strategy, i.e., the grouping and admission control algorithm. Simulation results show that users can obtain larger rates under the symmetric cooperation strategy than the non-cooperative case.

A robust model predictive control (MPC) algorithm is presented for a class of discrete-time uncertain systems with time-varying delay, input constraints and norm-bounded nonlinear perturbations. By minimizing the upper bound of a cost function, an MPC state feedback control law is calculated at each step. The proposed MPC method for delayed system is delay-dependent, and it is effective to deal with nonlinear perturbations. It has been shown that the robust stability of the closed-loop systems is guaranteed by the proposed algorithm. Finally, a numerical example is given to illustrate the effectiveness of the proposed method.
