It is necessary to consider the impact of demand uncertainty to model the comprehensive approach for supply chain network design. This paper presents four echelons, multiple commodity, and strategic–tactical model for designing supply chain network. Uncertain demand, transportation mode selection with lead time configuration has been considered. A numerical example has been implemented to verif...
Traffic congestion causes huge economic loss worldwide in every year due to wasted fuel, excessive air pollution, lost time, and reduced productivity. Understanding how humans move and select the transportation mode throughout a large-scale transportation network is vital for urban congestion prediction and transportation scheduling. In this study, we collect big and heterogeneous data (e.g., G...
Recent advances in transit modeling can provide detailed contact patterns for passengers of public transportation networks. A natural way to represent such patterns is in the form of graphs. In this paper we analyze the public transportation network of a major metropolitan area from a unique perspective. We present a novel network structure to identify and track the relationships between passen...
In recent years, disasters have an increasing impact on modern societies in terms of both economic and human losses. Following disasters, transportation networks act as key lifelines enabling access to the affected communities and supporting evacuation, emergency response, relief and recovery operations. In this context, this two-part survey offers a systematic review of papers related to trans...
