Many real life systems such as manufacturing, telecommunication, computers, and urban traffic systems can be modeled as capacitated-flow networks. The reliability and unreliability are two important indices to measure the quality level for a capacitated-flow network. For a multiple commodity (different types of commodity) capacitated-flow network with unreliable nodes, the arcs and nodes all ha...

proposing a robust designed facility location is one of the most effective ways to hedge against unexpected disruptions and failures in a transportation network system. this paper considers the combined facility location/network design problem with regard to transportation link disruptions and develops a mixed integer linear programming formulation to model it. with respect to the probability o...

The transport system is one of the main bottlenecks world’s largest producer and exporter soybeans, Brazil. Long-distance truck transportation grains increases costs, food waste, CO2 emissions. To handle these problems, Brazilian government seeks to expand through national logistics plan (PNLT), promoting efficient operations. Collaborating on environmental aspect, this paper proposes sustainab...

In the Vehicle Routing Problem with Pickup and Delivery (VRPPD), a set of transportation requests must be satisfied by capacitated vehicles based at one or several depots. Each request is defined by an origin (or pickup point), a destination (or delivery point), and a demand to be transported from the origin to the destination. Typical applications are parcel services and dial-a-ride transporta...

The Vehicle Routing Problem (VRP) deals with the assignment of a set of transportation orders to a fleet of vehicles and the sequencing of stops for each vehicle to minimize transportation costs. This paper presents two different genetic algorithm models (panmitic and cellular models) for providing solutions for the Capacitated VRP (CVRP), which is mainly characterized by using vehicles of the ...

In this paper, bi-level programming is proposed for designing a competitive supply chain network. A two-stage stochastic programming approach has been developed for a multi-product supply chain comprising a capacitated supplier, several distribution centers, retailers and some resellers in the market. The proposed model considers demand’s uncertainty and disruption in distribution centers and t...

The Vehicle Routing Problem (VRP) deals with the assignment of a set of transportation orders to a fleet of vehicles, and the sequencing of stops for each vehicle to minimize transportation costs. In this paper we study the Capacitated VRP (CVRP), which is mainly characterized by using vehicles of the same capacity. Taking a basic GA to solve the CVRP, we propose a new problem dependent recombi...

Smart cities make use of a variety smart technology to improve societies in better ways. Such intelligent technologies, on the other hand, pose significant concerns terms power usage and emission carbons. The suggested study is focused technological networks for big data-driven systems. With support software-defined transportation-aided multicast routing system suggested. By using public transp...

We present a new optimization model for the tactical design of scheduled service networks for transportation systems where several entities provide service and internal exchanges and coordination with neighboring systems is critical. Internal exchanges represent border crossings necessitating changes of vehicles, while the coordination with neighboring systems represents intermodal operations. ...
