3 COPA, Department of Industrial Engineering, Universidad de los Andes, Bogota, Colombia {amedagli, nvelasco}@uniandes.edu.co In the truck and trailer problem (TTRP), raised for instance by milk collection in rural areas, a heterogeneous fleet composed of mt trucks and mr trailers (mr < mt) serves a set of customers N = {1, 2, ..., n} from a main depot, denoted as node 0. Each customer i ∈N h...

Many professional truck drivers experience low back pain (LBP) which is believed to be associated with exposure to whole body vibration (WBV). As a part of a randomized controlled trial, this study measured WBV exposures from 98 professional truck drivers continuously during their regular work shift (8-12 hours). The daily weighted average A(8), vibration dose value VDV(8), and vector sum A(8) ...

The authors have been conducting development of an autonomous loading system by wheel loader. As a part of the development, a detection method of location of the dump truck will be described in this paper. In the process of loading to the truck in the operation, the loader approaches to the dump truck in very close distance. The function for collision avoidance between the loader and the truck ...

Motivated by a situation faced by infrastructure service providers operating in urban areas with accessibility restrictions, we study the truck and trailer routing problem with time windows (TTRPTW). In this problem the vehicle fleet consists of trucks and trailers which may be decoupled. A set of customers has to be served and some of the customers can only be accessed by the truck without the...

This paper describes P–Truck Curing, a Case Based Reasoning system supporting the design of the curing phase for truck tyre production. The design of this process provides a trade–off between an optimal curing degree, to avoid imperfections in the final product, and the reduction of costs, related to thermal energy employed in the curing. Expert curing process designers store information about ...

OBJECTIVES The purpose of this work was to investigate the fitness of the existing truck seats for Bangladeshi truck drivers and suggest a guideline for drivers' seats based on their anthropometry. METHODOLOGY In this study, eight anthropometric measurements of 120 Bangladeshi truck drivers and seven seat dimensions of ninety trucks of three brands namely, TATA, ASHOK LEYLAND, and ISUZU were ...

Berths and yards are the most critical parts of container terminals. Their efficiency directly influences terminal operation efficiency. The multi-period coordinated optimization on berth allocation yard assignment has been studied considering a interaction between yard. problem is formulated as an integer programming, aimed at minimizing total truck travel distance, where decision variables be...

A Neurointerface is a nonlinear filtering system based on Neural Networks that serves as a coupler between a human operator and a nonlinear system or plant that is to be controlled or directed. The purpose of the coupler is to ease the task of the human controller. A Neurointerface and a plant disturbance canceller have been applied to the steering system of a truck and trailer(s). The Neuroint...

China is a large agricultural country. With the development of industrial production, mechanized harvesting has become an inevitable trend material harvesting. In this paper, based on latest technology polycrystalline ferroelectric composite materials in design shovel frame harvester’s vibrating excavating shovel, relevant theories and are literature. After understanding, structure harvester wa...

This paper analyzes the feasibility of using cellular telephone location data to determine the geographic extent of trucks from intermodal facilities. The feasibility analysis includes three aspects: location technology, cell phone penetration, and truck tracking methodology. As the results shows, the cell phone location technology is able to provide accurate location data. It can provide updat...
