The resistant behavior of large-scale billboard should be taken into consideration while design. The mechanical behavior of large-scale billboard under lateral wind load is analyzed by numerical simulation of FEA and model test. It is a significant concept to enhance the torsion resistance ability of billboard structure in order to reduce the disaster under wind load. The most unfavorable wind load in certain direction is also pointed out. The relationship between stiffness and mass distribution and structure failure model is discussed. Results show that the vibration model is related to stiffness and mass distribution, column torsion is the key matter, which is proven by model test. This results can be used for reference in engineering design. [ABSTRACT FROM AUTHOR]

Aim at the problem of the performance analysis was emphasized particularly on the afterward methods such as performance monitor, management, and data analysis of the deployed processes, this paper analyzed the state-of-art of business process performance analysis and simulation optimization in detail. Then it proposed an IBPSM method that was compatible to the corresponding enterprise model and workflow model. It also designed a prototype system of the IBPSM-supported MBPST. Finally, it provided an application case. Practice shows that the multi-business process simulation based performance optimization method which is a beforehand method would support: the optimization and simulation of performance of business process; rapid IT implementation of business process after performance optimization.

This paper proposed a resource allocation scheme based on the coalitional game. First, it used an admission control mechanism to provide services of mobile applications to the users given the available long-term reserved resources in a pool. And it introduced an optimization formulation to obtain the optimal decision of admission control. Then, for a given coalition of service providers, the revenue obtained from utilizing the resource pool had to be game shared among the service providers. It developed a coalitional game model for sharing the revenue. The simulation results show that the proposed method is effective, which can obtain the optimal strategies of service providers on capacity expansion such that their profits are maximized.
