Strategic Optimization of Bus Systems with Stochastic Ridership
Haoran Zhao, Andres Fielbaum
In global metropolitan areas, public transport benefits from bus systems. Bus design widely applies theoretical models, which typically assume static ridership. However, ridership…
The Increasing Gap Dynamics in a General Spatial Matching Model
Andrés Fielbaum, Roberto Cominetti, José Correa
We study a representation of a problem that appears in numerous transport systems: servers distributed over a given space (e.g., cars on an urban network), receive random reque…
Analytical modeling of a stop-less modular bus line: Optimization, feasibility, and economies of scale
Haoran Zhao, Neema Nassir, Andres Fielbaum
Conventional bus services often struggle with inefficiencies including prolonged dwell times at heavily used stops, especially for through passengers. A stop-less autonomous modula…
Idle wage as a tool to regulate the relationship between ride-hailing platforms and drivers
Andrés Fielbaum, David Salas, Ruilin Zhang +1
Ride-hailing platforms typically classify drivers as either employees or independent contractors. These classifications tend to emphasize either wage certainty or flexibility, but…
Fleet Sizing for the Flash Delivery Problem from Multiple Depots a Case Study in Amsterdam
Maximilian Kronmueller, Andres Fielbaum, Javier Alonso-Mora
In this paper, we present a novel approach for fleet sizing in the context of flash delivery, a time-sensitive delivery service that requires the fulfilment of customer requests in…
Pooled Grocery Delivery with Tight Deadlines from Multiple Depots
Maximilian Kronmueller, Andres Fielbaum, Javier Alonso-Mora
We study routing for on-demand last-mile logistics with two crucial novel features: i) Multiple depots, optimizing where to pick-up every order, ii) Allowing vehicles to perform de…
New sources of economies and diseconomies of scale in on-demand ridepooling systems and comparison with public transport
Andres Fielbaum, Alejandro Tirachini, Javier Alonso-Mora
On-demand ridepooling (ODRP) can become a powerful alternative to reduce congestion and emissions, if it attracts private car users. Therefore, it is crucial to identify the strate…
Anticipatory routing methods for an on-demand ridepooling mobility system
Andres Fielbaum, Maximilian Kronmuller, Javier Alonso-Mora
One of the most relevant challenges regarding on-demand ridepooling relates to the spatial imbalances of the demand, which induce a mismatch between the position of the vehicles an…
How to split the costs among travellers sharing a ride? Aligning system's optimum with users' equilibrium
Andres Fielbaum, Rafal Kucharski, Oded Cats +1
How to form groups in a mobility system that offers shared rides, and how to split the costs within the travellers of a group, are non-trivial tasks, as two objectives conflict: 1)…
A Water-Filling Primal-Dual Algorithm for Approximating Non-Linear Covering Problems
Andrés Fielbaum, Ignacio Morales, José Verschae
Obtaining strong linear relaxations of capacitated covering problems constitute a major technical challenge even for simple settings. For one of the most basic cases, the Knapsack-…
