Transportation has an important role in the logistics of a company, both services and products. Increased orders 2020 for wooden speaker products at CV. XYZ (Wonoayu-Sidoarjo) makes this company try to minimize transportation costs their operational level. This study focuses on determining relationship between changes type fleet vehicle depot location product delivery time return terms adding t...

Behavioural and mathematical problems in the current formulation of the asymmetric multiclass traac assignment model are brought to light. A new formulation is presented that resolves these diiculties. The formulation is quantiied, and the result is a general class of coherent, multiclass cost functions. A numerical calibration exercise for a car and truck class model concludes the paper.

regulated by the corporate average fuel economy (CAFE) standards, established during the energy crises of the 1970s. Calls to increase fuel economy are usually met by a fierce debate on the effectiveness of the CAFE standards and their impact on highway safety. A seminal study of the link between CAFE and traffic fatalities was published by R. W. Crandall and J. D. Graham in 1989. They linked h...

This research aimed to analyze the effect on energy saving of trucks in transport and logistics business by monitoring evaluating truck drivers. A sample seventy-four 10-wheel was selected. Fuel consumption data collected from drivers as they operated their vehicles using GPS systems. The results suggested a total reduction fuel with improved rates. Annual mileage affected better saving: high a...

We consider optimizing a truck's choice of path and speed profile to minimise fuel consumption, exploiting real-time predictive information on dynamically varying traffic conditions. Time-varying conditions provide particular challenges, both from network-level interactions (e.g. slowing consume more locally may be beneficial avoid congested periods downstream) link-level phenomena interaction ...

In order to develop original and efficient visible light response photocatalysts for degrading organic pollutants in wastewater, new photocatalysts Bi₂GaSbO₇ and Bi₂InSbO₇ were firstly synthesized by a solid-state reaction method and their chemical, physical and structural properties were characterized. Bi₂GaSbO₇ and Bi₂InSbO₇ were crystallized with a pyrochlore-type structure and the lattice p...

Truck platooning for the transportation of loads is a strategy recently proposed by automotive sector to cope with traffic congestion, fuel consumption, and operational costs. This new way configuring trucks changes typical pressures pavements structures experience. For this reason, research efforts pavement should be aligned propose road-friendly platoon configurations. one objectives European...

The Truck Factor designates the minimal number of developers that have to be hit by a truck (or quit) before a project is incapacitated. It can be seen as a measurement of the concentration of information in individual team members. We calculate the Truck Factor for 133 popular GitHub applications, in six languages. Results show that most systems have a small truck factor (46% have Truck Factor...

Objectives • Elucidate rates and mechanisms of the degradation of polymer electrolyte fuel cell (PEFC) platinum electrode performance – Effect of electrolyte, potential (holding and cycling), time, and temperature • Develop non-platinum cathode electrocatalysts for PEFCs – Transition metal carbides and nitrides – Bi-metallic systems – Metal centers attached to electron-conducting polymer backbones
