Although today’s Internet predominantly uses the flat-fee pricing scheme, the need for more sophisticated pricing has grown, especially for domains where bandwidth resources are scarce and expensive. This paper focuses on how to determine the price vector that maximizes the system revenue in priority-based networks. Similar problems have been examined using equilibrium analysis, but the assumpt...

Optical networks provide a new dimension to meet the demands of exponentially growing traffic. Optical packet switching requires a good switch architecture, which eliminates the O/E/O conversion as much as possible. Wavelength Division Multiplexing (WDM) provides a breakthrough to exploit the huge bandwidth of the optical fiber. Different applications have different requirements, which necessit...

In this paper, we propose a new methodology of multidimensional poverty measurement. Our approach is based on using self-stated responses to household spending priorities. This information is first used to know what the relevant deprivations are. In particular, the stated top priorities allow us to identify the poor. For each household, the deprivations are aggregated according to relative weig...

logistic network design is one of the most important strategic decisions in supply chain management that has recently attracted the attention of many researchers. transportation network design is then one of the most important fields of logistic network. this study is concerned with designing a multi-stage and multi-product logistic network. at first, a mixed integer nonlinear programming model...
