OS Circular is a framework for Internet Disk Image Distribution of software for virtual machines, those which offer a ‘‘virtualized’’ common PC environment on any PC. OS images are obtained via the stackable virtual disk ‘‘Trusted HTTP-FUSE CLOOP’’. The system is designed to utilize Mirror servers and Proxies for highly-scalable worldwide deployment. OS Circular easily and efficiently handles b...

In this paper, we propose a simultaneous approach to incorporate inventory control decisions––such as economic order quantity and safety stock decisions––into typical facility location models, which are used to solve the distribution network design problem. A simultaneous model is developed considering a stochastic demand, modeling also the risk pooling phenomenon. We present a non-linear-mixed...

a comprehensive and integrated study of any supply chain (sc) environment is a vital requirement that can create various advantages for the sc owners. this consideration causes productive managing of the sc through its whole wide components from upstream suppliers to downstream retailers and customers.  on this issue, despite many valuable studies reported in the current literature, considerabl...

The facility location problem consists of a set of facilities F , a set of clients C, an opening cost fi associated with each facility xi, and a connection cost D(xi, yj) between each facility xi and client yj . The goal is to find a subset of facilities to open, and to connect each client to an open facility, so as to minimize the total facility opening costs plus connection costs. This paper ...

Plug-in electric vehicles (PEVs) represent a huge step forward in a green transportation system, contribute in reduction of greenhouse gas emission, and reduce the dependence on fossil fuel. Integration of PEVs into the electric power system will result in a considerable addition to electricity demand. Due to PEV mobility, this demand has a random distribution in space and time among distributi...

in this paper, we study wsn design, as a multi-objective optimization problem using ga technique. we study the effects of ga parameters including population size, selection and crossover method and mutation probability on the design. choosing suitable parameters is a trade-off between different network criteria and characteristics. type of deployment, effect of network size, radio communication...

An accurate estimation of network performance is critical for the success of optical networks design. Traffic modeling and availability modeling for optical network are at heart of optical network design. Traffic models and availability models need to be accurate and able to capture the statistical characteristics of the actual traffic and the ability of a network to sustain failures. However, ...

This paper describes Trellis, a software platform for hosting multiple virtual networks on shared commodity hardware. Trellis allows each virtual network to define its own topology, control protocols, and forwarding tables, which lowers the barrier for deploying custom services on an isolated, reconfigurable, and programmable network, while amortizing costs by sharing the physical infrastructur...

This paper is focused on the optimised design of a distribution network taking into account the variability of the final customer demand. In particular we study the design of a one-to-many distribution system, considering the product flows from the hub to the different transit points, as well as the reverse flows. The optimization procedure consists of two main steps: the first step is the dete...
