Network science, or the art of describing system structure, may be useful for the analysis and control of large, complex systems. For example, networks exhibiting scale-free structure have been found to be particularly well suited to deal with environmental uncertainty and large demand growth. Changes in the demand for air transportation are inevitable, and indeed seem to be upon us. The Nation...

DynaMIT is a simulation-based real-time system designed to estimate the current state of a transportation network, predict future tra c conditions, and provide consistent and unbiased information to travelers. To perform these tasks, e cient simulators have been designed to explicitly capture the interactions between transportation demand and supply. The demand re ects both the OD ow patterns a...

In this paper, sensitivity analysis of supply and demand parameters of an interval transportation problem is presented. A new solution method namely, upper-lower method is proposed to determine the ranges of supply and demand parameters in an interval transportation problem such that its optimal basis is invariant. To illustrate the proposed method a numerical example is solved. Then, the upper...

In this article we present an algorithm for converting a network problem with several sources and several sinks including several transfer nodes and condition of supplying the demand of any sink from a particular source to the transportation problem.  Towards this end, and considering the very special structure of transportation algorithm, after implementing the shortest path algorithm or ...

The purpose of this paper is to solve the stochastic demand for unbalanced transport problem using heuristic algorithms obtain optimum solution, by minimizing costs transporting gasoline product Oil Products Distribution Company Iraqi Ministry Oil. most important conclusions that were reached are results prove possibility solving random transportation when uncertain programming model. obvious f...

Development of technology has made possible the invention of innovative and modern methods to solve partially the problems caused by traffic congestion, through decreasing the need for physical transportation; one such method being telecommuting. Few predictions have been reported regarding its aggregate demand at the level of a city, generally because of the complexity and multi-dimensionality...
