For the status that researches on customers' utility merely take up a small proportion in the studies on the cloud resource allocation, this paper proposes a cloud allocation model borrowing the idea of Network Utility Maximization(NUM)model, which maximizes the customers' utility. The model can be simplified to the Lagrangian dual function by the Lagrange function. Finally, a fuzzy subgradient algorithm...
A class of wireless multicast utility optimization problems are considered. Assume network utility is only a function of link throughput and nodes' transmission power. Under a set of physical layer assumptions, the impact of physical and data-link layer configurations to the upper layers in a wireless network can be characterized using a configuration graph. Network layer utility optimization can...
Having set up the finite element model based on some type and one pair of frames of fire engine of ANSYS, and has carried on the stress of imitating the actual operating mode and calculated and tested proving. Proceed from analysis results of finite element, has formed the mathematics model of optimization design, put forward the comparatively rational light design plan of quantization of pairs of...
