In order to effectively solve the problem of vehicle routing, a design and implementation method an energy-saving logistics management system oriented routing optimization is proposed. From perspective optimal calculation, this research uses improved Dixie algorithm clustering implement company’s distribution center location path planning system. First all, authors analyze common models LRP in ...

Electric commercial vehicles can contribute significantly to sustainable transportation. However, they are still perceived as being less economically viable than internal combustion engine vehicles. To this end, we analyze the deployment of electric in retail mid-haul logistics fleets for current and future technology scenarios. We develop a novel assessment methodology that combines total cost...

the capacitated vehicle routing problem (cvrp) is a well-known combinatorial optimization problem that holds a central place in logistics management. the vehicle routing is an applied task in the industrial transportation for which an optimal solution will lead us to better services, save more time and ultimately increase in customer satisfaction. this problem is classified into np-hard problem...

In this paper we examine five different strategies for limiting the local search neighborhoods in the context of vehicle routing problems. The vehicle routing problem 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. The examined strategies are applied to four standard neighborhoods ...

Electric vehicles (EVs) are widely applied in logistics companies’ urban distribution, as fuel prices increase and environmental awareness grows. This study introduces an EV charging station (CS) location-routing problem with time windows resource sharing (EVCS-LRPTWRS). Resource sharing, among multiple depots within service periods is proposed to adjust the transportation configuration for a s...

The Tor network provides low-latency anonymous communication to over two million users daily. To be practical for widespread use, Tor uses onion routing, which does not protect a user against an adversary that can observe a user’s traffic at certain vulnerable positions along the traffic’s route through the Internet. A natural defense would be to choose Tor relays to minimize the chance that th...

Determining optimal routes for given freight is a core decision in logistics. In intermodal logistics, freight routing has to consider the interfaces between different modes of transportation, such as hand-over offsets, load changes, and organizational procedures. We study this problem from the perspective of Service-Oriented Computing (SOC). We (1) propose representing intermodal transport sys...

Intermodal freight transportation is concerned with shipping of commodities from their origin to destination using combinations of transport modes. Traditional logistics models have concentrated on minimizing transportation costs by appropriately determining the service network and the transportation routing. This paper considers an intermodal transportation problem with an explicit considerati...

The authors have developed a mobile, autonomous decentralized utility system for indoor transportation, called AMADEUS. This paper explains how we put it to practical use. AkL4DEUS is a system designed around transportation agents. We eliminated centrally managed vehicle allocation and routing plans by implementing autonomous vehicle allocation negotiations and collision avoidance between agent...

Many important problems in communication networks, transportation networks, and logistics networks are solved by the minimization of cost functions. In general, these can be complex optimization problems involving many variables. However, physicists noted that in a network, a node variable (such as the amount of resources of the nodes) is connected to a set of link variables (such as the flow c...
