This study presents a multimodal hub location problem which has the capability to split commodities by limited-capacity hubs and transportation systems, based on the assumption that demands are stochastic for multi-commodity network flows. In the real world cases, demands are random over the planning horizon and those which are partially fulfilled, are lost. Thus, the present study handles dema...

Not all virtual reality applications today require the power or expense of single large visualization “supercomputers”. Factors such as frame rate and polygon count have a major impact upon the performance of a VR application. Increasingly, low cost commodity consumer electronics and computing technology are becoming powerful enough to present an acceptable level of graphics performance. Alread...

We propose a macroscopic modeling framework for a network of roads and multi-commodity traffic. The proposed framework is based on the Lighthill-Whitham-Richards kinematic wave theory; more precisely, on its discretization, the Cell Transmission Model (CTM), adapted for networks and multicommodity traffic. The resulting model is called the Link-Node CTM (LNCTM). In the LNCTM, we use the fundame...
