Heavy-vehicle driving involves a challenging work environment and a high crash rate. We investigated the associations of sleepiness, sleep disorders, and work environment (including truck characteristics) with the risk of crashing between 2008 and 2011 in the Australian states of New South Wales and Western Australia. We conducted a case-control study of 530 heavy-vehicle drivers who had recent...

Cross docking terminals allow companies to reduce storage and transportation costs in a supply chain. At these terminals, products of different types from incoming trucks are unloaded, sorted, and loaded to outgoing trucks for delivery. If the designated outgoing truck is not immediately available for some products, they are temporarily stocked in a small storage area available at the terminal....

The multipurpose terminal in a port, is an intermodal platform that links the ship to the truck, or to another vessel in the case of transshipment. This paper presents an approach which aims to optimize the massive volumes processing of goods in order to arrive at a reduction in the time loading trucks, specifically; to reduce the time between the tare weighing and loaded truck. In order to ach...

Because the transport expenses are more than a half the national logistics expenses, the increase of the transport expenses becomes the cause of an increase of national logistics expenses. To decrease of the logistics expenses, it has to develop logistics management application. Many Transport Companies are serving monitoring position of the transport vehicle, but the position data of the movin...

The main objective of this study is to evaluate the workability of fresh portland cement concrete while it is still in the mixing truck by determining fundamental rheological parameters (plastic viscosity and yield stress). Nine concrete mixtures with different values of yield stress and plastic viscosity were tested in a concrete truck. The measurements made with the truck were based on the ty...

Abstract Application of memetic algorithm (MA) is considered in this work to solve the truck and trailer routing problem (TTRP). In TTRP, some customers can be designated as vehicle customers and can be serviced either by a complete vehicle (a trailer pulling by truck) or a single truck. However, some customers are known as truck customers and have to be serviced by a single truck. To employ t...

This paper considers the effectiveness of a truck appointment system in improving the yard efficiency of the container terminal. This research uses truck appointment information to improve the import container retrieval operation and reduce container rehandles by adopting an advanced container location assignment algorithm. By reducing the container rehandles, the terminal could improve yard cr...

In the present paper, the idea of braking energy regeneration and reusing that energy during acceleration for a refuse truck is comprehended. According to their driving cycle, the refuse trucks have a good potential for braking energy regeneration. On the other hand, hydraulic hybrid is a powertrain with high power density which is appropriate for energy regeneration. In the primary stage of th...

Truck and shovel are the most common raw material transportation system used in the cement quarry operations. One of the major challenges associated with the cement quarry operations is the efficient allocation of truck and shovel to the mining faces. In order to minimize the truck and shovel operating cost, subject to quantity and quality constraints, the mixed integer linear programing (MILP)...
