The simulation technology of 3G mobile communication network is a very important part of network researching. It can increase researching efficiency and decrease developing cost of network. At first, in this paper, we have discussed producing method of some kinds of stochastic numbers, include heavy- tail distributing stochastic numbers, which often used in network simulation. We have also introduced...
Physical structure are compared between air-water plate heat exchangers (PHE) and tube-fin type heat exchangers in this paper, which show that the air-water PHE has the stable character in handling the cold air below 0degC because of its compact and knock-down structure. Then the courses of water being iced in the motionless state and in the flowing state were simulated by the CFD software Fluent...
In practice, partner selection in agile supply chain network usually involves multi-stages instead of one. In this paper, it is shown that this problem can be represented as a directed graph model. The natures of the proposed model enable us to design a meta-heuristic algorithm - GACA which combined the pros part of ACOA and GA for solving the good path search problem. Computational results show the...
