the capacitated vehicle routing problem (cvrp) is a well-known combinatorial optimization problem that holds a central place in logistics management. the vehicle routing is an applied task in the industrial transportation for which an optimal solution will lead us to better services, save more time and ultimately increase in customer satisfaction. this problem is classified into np-hard problem...

the suspension system of a vehicle is one of the most important parts which is involved in the process of vehicle designing. when a vehicle suspension system is designed, the evaluation of its performance against the road disturbances such as shocks and bumps are very important. the most commonly used systems consist of four hydraulic jacks with mobility in vertical line with low speed and low ...

In this paper, we propose a novel research scheme to solve the single vehicle pickup and delivery problem (PDPTW) with time window constraints. The family competition genetic algorithm (FCGA) is a modern approach that has been successfully applied to solve the traveling salesman problem. We illustrate the family competition GA and give the experimental results that show the FCGA is a brilliant ...

Two kinds of configuration schemes about eight and ten single-axis vector magnetometers are put forward on the basis of describing the principle of underwater magnetic field localization. The measurement equations of magnetic field magnitude and gradients are educed on condition of two configuration schemes, and that the calculated precisions of both magnetic field magnitude and gradients are c...

When designing a vehicle, the most important variable that should be taken into account is vehicle yaw rate, it represents an indication of vehicle’s stability and control. This paper aims to demonstrate how simulate control rate using two methods, first Linear Quadratic method (LQR) other one neural network The classical single-track model prominently used for analysis. One driving conditions ...

This research presents a non-isolated multi-port power converter feasible to hybridize energy alternatives in electric vehicles. Due the hybridization of various input sources, there are several advantages load distribution system. Flexible control discharging as well charging process concerning sources can be achieved. The developed able boost voltage levels with dual inputs such renewable sol...

Electric vehicles offer a promising solution to solving environmental problems related air pollution. The typical powertrain design of an electric vehicle includes relatively high-speed-low-torque motor integrated with some mechanical system transmit the output energy wheels, such as gearbox, transmission and differential. Different drivetrain configurations single, double quad motors can be us...
