This study evaluates different strategic courses of action concerning the secondary transportation sector in Hyrcanian forests of Iran. The decision support method Analytic Hierarchy Process (AHP) has been utilized in the assessment of different strategies in truck selection. The assessments are based on the opinions of a group of experts in Iranian forest industries. Results showed that the tr...

initially, the first aim of the present study is to model 3-axle rigid truck by developing a code inmatlab. secondly, each equation should be drived by acquisition of lagrange approach. afterderiving equations successfully, validation is performed by some result which was mentioned inbohao li's master thesis. although the present approach is totally different from the approachthat boahao li use...

Transport Canada’s Dangerous Goods Directorate (TDG) data base of crashes involving a vehicle carrying dangerous goods shows 810 rollovers in 1,874 reported crashes from 1990 to 1998, and 83% of these involved highway tank trucks. TDG is therefore considering approaches to improve the rollover stability of tank trucks used for highway transportation of dangerous goods. TDG asked the Centre for ...

In this paper we steer wheeled nonholonomic systems that can be represented in a so called chained form Su cient conditions for converting a multiple input system with nonholonomic velocity constraints into a multiple chain single generator chained form via state feedback and a coordinate transformation are presented along with sinusoidal and polynomial control algorithms to steer such systems ...

The capacitated vehicle routing problem with sequence-based pallet loading and axle weight constraints is an extension of the classical Capacitated Vehicle Routing Problem (CVRP). It integrates loading constraints in a routing problem and is based on a real-world transportation problem. The demand of the customers consists of pallets. These pallets may be placed in two horizontal rows inside th...

in order to study the effects of sugar cane harvest machinery traffic on bulk density and cone index variation, a survey was conducted in 10 farms of deabel khozaiee sugarcane agro-industrial company, ahvaz, in 2006. in this experiment, two types of harvesters including wheel half track and tire wheels with 14 tons of weight, versus two types of tractor and basket transporters, with 10 and 18 t...

Abstract Impacts of autonomous truck’s passes on pavement have been analyzed in this research. Two types lateral positioning namely zero wander and uniform along with a super single wide tire dual variable traffic speeds ABQUS. The study concludes the results favor usage under mode. highest amount damage terms maximum rut depth is caused by wheel assembly moving zero-wander magnitude increases ...
