The optimal truck configuration for a certain customer is very specific and depends on for what transport mission and in which operating environment the truck is to be used. In addition, the customers normally specify other feature requirements ranging from visual appearance to advanced driver support systems. For this reason, the truck configurations that are made available for the customers a...

EA4T steel has been widely used in the manufacture of railway axles. Laser cladding remanufacturing technology to repair axles, and failure behaviors axles studied. In this work, a class original FeCrNiMo alloy layers that contain rare-earth elements was successfully fabricated through laser technique on substrates. The microstructure elemental distribution were analyzed scanning electron micro...

The deployment of large machinery for low cost, bulk surface mine production operations has resulted in High-Impact Shovel Loading Operations (HISLO). In extreme cases, shovels load large dump trucks with 100ton (or more) passes generating high-impact forces under gravity. HISLO generates high-frequency shockwaves that cause severe truck vibrations exposing operators to Whole Body Vibrations (W...

We present Tabu Search based solution heuristics for the Timber Transport Vehicle Routing Problem (TTVRP) that differ with respect to solution space. The TTVRP is characterized as follows: a fleet of m log-trucks which are situated at the respective homes of the truck drivers has to fulfil n transports of round timber between different wood storage locations and industrial sites. All transports...

This report addresses an important crossdocking planning operation which is the scheduling of trucks at crossdocking terminals. The study focuses on the problem in a resource-constrained crossdock. The truck scheduling problem in this scenario decides on the succession of incoming and outgoing trucks at the dock doors of the crossdocking terminal, subject to the availability of the crossdock re...

The role of ports goes far beyond the traditional function of a pure transport node linking sea and landside transportation. Rather, many ports offer value-added logistics and auxiliary services leading to a network of container flows. Moreover, containers may need to be transferred between different areas within the port. Information exchange and optimization is necessary to efficiently coordi...

The management of trucks in a cross-docking platform is a process under five steps: the arrival, the control, the unloading, the transfer and finally the loading. In each of these steps, a sequence of decisions arise. To achieve an optimal and robust solutions, the interdependencies between the different planning functions should be taken into account, and scheduling decisions must be made simu...

The Federal Highway Administration (FHWA) Office of Highway Planning requires states to furnish vehicle classification data as part of the Highway Performance Monitoring Systems (HPMS). To comply with this requirement, most states use the “F-Scheme” to classify vehicles. This scheme classifies vehicles in 13 classes depending on a number of factors, primarily the number of axles and the axle sp...
