Dynamic programming algorithm for the vehicle routing problem with time windows and EC social legislation [PDF]

open access: yes, 2009
In practice, apart from the problem of vehicle routing, schedulers also face the problem of nding feasible driver schedules complying with complex restrictions on drivers' driving and working hours.

Routing Unmanned Vehicles in GPS-Denied Environments

open access: yes, 2017
Most of the routing algorithms for unmanned vehicles, that arise in data gathering and monitoring applications in the literature, rely on the Global Positioning System (GPS) information for localization.

NDST3‐Induced Epigenetic Reprogramming Reverses Neurodegeneration in Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
NDST3‐mediated epigenetic reprogramming revitalizes neuronal circuits in the substantia nigra and striatum to halt dopaminergic neuron degeneration and restore motor function in Parkinson's disease models. This strategy promotes neuronal maintenance and functional recovery, highlighting NDST3's therapeutic potential in neurodegenerative disorders ...

Ecosystem‐Centered Robot Design: Toward Ecoresorbable Sustainability Robots (ESRs)

open access: yesAdvanced Science, EarlyView.
Robots exploring natural ecosystems can support monitoring and conservation, but must adopt ecosystem‐centered design to avoid pollution, waste, and damage. This review proposes guidelines for co‐designing ecoresorbable sustainability robots (ESRs), uniting materials, robotics, and ecological contexts in a single framework.

Optimal multi-depot location decision using particle swarm optimization

open access: yesAdvances in Mechanical Engineering, 2017
The depot locations have a significant effect on the transportation cost in the multi-depot vehicle routing problem. A two-tier particle swarm optimization framework is proposed, in which an external particle swarm optimization and an internal particle ...

Arc routing vehicle routing problems with vehicle/site dependencies [PDF]

open access: yes, 1996
In this paper, an algorithm is discussed for solving the Vehicle Arc Routing Problem when there exists the constraints of Vehicle/Site Dependencies. The traditional Capacitated Arc Routing Problem assumes a homogeneous fleet mix of vehicles available to service the arcs in the network.
