PRYORTIE: Public on-demand smart transportation service via a scalable fog-based platform
Intelligent Systems with Applications, 2023 Over the past few years, the on-demand transport services (e.g., Uber) have witnessed an unprecedented popularity due to its easy-to-adopt model (i.e., a passenger orders a taxi, a request is sent to all drivers in the vicinity, drivers accept/reject the

Improved Approximation Algorithm for Steiner k-Forest with Nearly Uniform Weights [PDF]
, 2014 In the Steiner k-Forest problem we are given an edge weighted graph, a collection D of node pairs, and an integer k leq |D|. The goal is to find a minimum cost subgraph that connects at least k pairs.

The on-demand bus routing problem with real-time traffic information
Multimodal Transportation, 2023 We propose to solve a real-time traffic variation of the On-Demand Bus Routing Problem (ODBRP) introduced by Melis and Sörensen (2022). The ODBRP belongs to the category of the Dial-A-Ride Problems (DARP), and features departure and arrival bus station ...

Goal Programming Approach for Carrying People with Physical Disabilities
Promet (Zagreb), 2020 Most of today's optimization efforts aim to reduce costs, time or the number of resources used. However, optimization efforts should consider other factors as important as these, such as facilitating the lives of the disabled, elderly and pregnant and ...

A Hybrid Adaptive Large Neighborhood Heuristic for a Real-Life Dial-a-Ride Problem
Algorithms, 2019 The transportation of elderly and impaired people is commonly solved as a Dial-A-Ride Problem (DARP). The DARP aims to design pick-up and delivery vehicle routing schedules.

Long-Distance Directional Dial-a-Ride Problems
Proceedings of the 9th International Conference on Vehicle Technology and Intelligent Transport Systems, 2023 We consider vehicle routing problems that occur in practice in the context of long-distance ride-sharing. On the one hand, the instances of our problems share the helpful property that the passengers travel in roughly the same geographical direction. On the other, the required cost function has ordering-dependent components.

Leveraging Public Transit for Robotic Deliveries: A Column Generation Approach
Naval Research Logistics (NRL), EarlyView.ABSTRACT Autonomous mobile robots (AMRs) are small, electric, wheeled vehicles that operate at pedestrian speeds. In the last‐mile delivery service considered in this study, a fleet of AMRs is deployed across multiple recharging depots within a service area, from which they depart to perform point‐to‐point deliveries. We consider an operational setting
