The time‐consistent dial‐a‐ride problem [PDF]
Networks, 2021 AbstractIn the context of door‐to‐door transportation of people with disabilities, service quality considerations such as maximum ride time and service time consistency are critical requirements. To identify a good trade‐off between these considerations and economic objectives, we define a new variant of the multiperiod dial‐a‐ride problem called the ...

The Integrated Dial-a-Ride Problem
Public Transport, 2008 In this paper we present a formulation of the Integrated Dial-a-Ride (IDARP). This problem is to schedule dial-a-ride requests, where some part of each journey may be carried out by a fixed route service. The IDARP is a generalization of the Dial-a-Ride Problem.

Revenue Maximization in Online Dial-A-Ride. [PDF]
, 2017 We study a variation of the Online-Dial-a-Ride Problem where each request comes with not only a source, destination and release time, but also has an associated revenue. The server's goal is to maximize its total revenue within a given time limit, T. We show that the competitive ratio is unbounded for any deterministic online algorithm for the problem.

The dial-a-ride problem with fairness
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2018 In the dial-a-ride problem, DARP for short, given a set of requests on pick up and delivery, we aim at finding a minimum-cost set of vehicle routes that meets all the requests.

Modeling and Optimizing Dynamic Dial‐a‐Ride Problems
International Transactions in Operational Research, 2001 Dial‐a‐ride is an emerging alternative to traditional public transportation systems. The aim of this paper is to reduce the gap between the models studied in optimization literature and the requirements of practical applications. We also describe the algorithms implemented in DARIA, a PC program for the optimization of static and dynamic dial‐a‐ride ...

The assignment-dial-a-ride-problem
Health Care Management Science, 2023 In this paper, we present the first Assignment-Dial-A-Ride problem motivated by a real-life problem faced by medico-social institutions in France. Every day, disabled people use ride-sharing services to go to an appropriate institution where they receive personal care. These institutions have to manage their staff to meet the demands of the people they

Future Transportation, 2023 Demand-Responsive Transport (DRT) is one of the most valid solutions to tackle the problems affecting public transport today, both in urban and rural areas. Despite its undoubted advantages, it still remains underdeveloped compared to its great potential.
