This research present a set-partitioning heuristic to generate populations in a hybrid genetic algorithm (hGA) which is able to solve four different variants of the vehicle routing problem: the multi-depot vehicle routing problem (MDVRP), the heterogeneous fleet and mix decisions (type, size and number of vehicle) (HFMVRP), site dependent vehicle routing problem (SDVRP) and the asymmetric vehic...

A vehicle routing problem is a significant problem that has attracted great attention from researchers in recent years. The main objectives of the vehicle routing problem are to minimize the traveled distance, total traveling time, number of vehicles and cost function of transportation. Reducing these variables leads to decreasing the total cost and increasing the driver's satisfaction level. O...

This paper aims to find the efficient state of hybrid electric vehicle (HEV) by simultaneous optimization of the control strategy and the power train. The power transmission employed in this vehicle is a power-split continuously variable transmission (CVT) which uses several fixed ratio mechanisms. After describing this transmission, the rules of electric assist control strategy are introduced....

VPSET (Vehicle Powertrain Systems Evaluation Tool) is vehicle modeling and simulation software to analyze performance and fuel economy of conventional and hybrid powertrains. VPSET has a Graphical User Interface (GUI) to guide the user during building a vehicle model. This paper discusses VPSET, its organization, structure, vehicle templates and presents validation results for select vehicles.

Using electrical machine in conventional vehicles, also called hybrid vehicles, has become a promising control scheme that enables some manners for fuel economy and driver assist for better stability. In this paper, vehicle stability control, fuel economy and Driving/Regeneration braking for a 4WD hybrid vehicle is investigated by using an electrical machine on each non-driven wheels. In front ...
