UNLABELLED As part of the 2010 Van Nuys tunnel study, researchers from the University of Denver measured on-road fuel-specific light-duty vehicle emissions from nearly 13,000 vehicles on Sherman Way (0.4 miles west of the tunnel) in Van Nuys, California, with its multispecies Fuel Efficiency Automobile Test (FEAT) remote sensor a week ahead of the tunnel measurements. The remote sensing mean gr...

In this paper is researched how to achieve an effective fleet maintenance planning in transport companies, which contributes in increasing the fleet energy efficiency and in achieving the companies’ goal. Within the fleet maintenance planning, managers have to make the right decisions on the selection of vehicle service centers in the region where the maintenance work will be realized. The ment...

Earthmoving operations often involve a large number of specially designed equipment with significant purchasing/leasing prices, high operating and maintenance costs. Hence, choosing the right fleet is a major concern from the construction planners’ point of view. This paper presents a methodology that combines discrete-event simulation and optimization to solve the optimal fleet selection probl...

Vehicle fleet modeling is a useful tool to analyze the dynamics of motor vehicles and their environmental impact at a macroscopic level, and has been applied in the USA and Europe. In this article, a road fleet model is constructed for the city-state Singapore. Policies that control vehicle ownership and congestion road pricing employed since 1998 differentiate Singapore’s vehicle market from o...

Ruiz-Vanoye et al. show a practice case of strategic planning for the computer science security based on the concepts of strategic administration of enterprise politics. The practice case of the computer science security shows information about an Electric Research Institute of Mexican Government. The Electric Research Institute is a public enterprise dedicated to innovation, technological deve...

In this communication the ground handling fleet management problem at airports is considered with the aim of improving aircraft service at arrival and departure while the operational cost of the ground service fleets is taken into account. The complexity of the considered problem, as well as, operational considerations lead to propose an on-line decentralized management structure where the crit...

The constant growth of cargo and passenger air transportation, their trends, as well laws on noise harmful emissions requirements make it possible to create a modern aircraft increased range carrying capacity. In this paper, the analysis volume existing fleet forecast its development is carried out, proposed consider features formation for an payload flight range. such will speed up design proc...

This paper presents a comparison of CO2 products derived from Scanning Imaging Absorption Spectrometer for Atmospheric Cartography (SCIAMACHY), Greenhouse Gases Observing Satellite (GOSAT) and Atmospheric Infrared Sounder (AIRS), with reference to calibration data obtained using the high-resolution ground-based Fourier Transform Spectrometers (g-b FTS) in the Total Carbon Column Observing Netwo...

A team from the Naval Postgraduate School conducted a trade-off analysis of in-sourcing (i.e., make) versus outsourcing (i.e., buy) the production of legacy parts for ship maintenance and modernization with a focus on cost savings given the need for cost-effective sustainment. The purpose of the study was to compare the make/buy trade-off for a comparison of implementing 3DLST, 3DP, and CPLM fo...
