When a natural disaster occurs, road maintenance departments always face the challenge of how to assign repair resources properly recover damaged segments as soon possible. From literature review, most studies treat such problems vehicle routing problem (VRP). In those studies, are dispatched complete crews, and cannot be divided into smaller scales. Furthermore, each point is only allowed one ...

The application of the Immersed Boundary ~IB! method to simulate incompressible, turbulent flows around complex configurations is illustrated; the IB is based on the use of non-body conformal grids, and the effect of the presence of a body in the flow is accounted for by modifying the governing equations. Turbulence is modeled using standard Reynolds-Averaged Navier-Stokes models or the more so...

The lack of multistakeholder cooperation is one the main challenges faced by emergency medical services (EMS). Especially in ambulance routing process, inactive traffic operators fail to provide coordination prioritize ambulance, while ignoring choice hospitals will lead inevitable patient transfer between hospitals. To efficient decision support for EMS, this paper considers daily problems a n...
