Hub-Based Platoon Formation: Optimal Release Policies and Approximate Solutions
Alexander Johansson, Ehsan Nekouei, Xiaotong Sun +2
This paper studies the optimal hub-based platoon formation at hubs along a highway under decentralized, distributed, and centralized policies. Hubs are locations along highways whe…
Swarm Bug Algorithms for Path Generation in Unknown Environments
Alexander Johansson, Johan Markdahl
In this paper, we consider the problem of a swarm traveling between two points as fast as possible in an unknown environment cluttered with obstacles. Potential applications includ…
Large-Scale Multi-Fleet Platoon Coordination: A Dynamic Programming Approach
Ting Bai, Alexander Johansson, Karl Henrik Johansson +1
Truck platooning is a promising technology that enables trucks to travel in formations with small inter-vehicle distances for improved aerodynamics and fuel economy. The real-world…
Approximate Dynamic Programming for Platoon Coordination under Hours-of-Service Regulations
Ting Bai, Alexander Johansson, Karl Henrik Johansson +1
Truck drivers are required to stop and rest with a certain regularity according to the driving and rest time regulations, also called Hours-of-Service (HoS) regulations. This paper…
A Pricing Rule for Third-Party Platoon Coordination Service Provider
Ting Bai, Alexander Johansson, Shaoyuan Li +1
We model a platooning system including trucks and a third-party service provider that performs platoon coordination, distributes the platooning profit within platoons, and charges…
Truck Platoon Formation at Hubs: An Optimal Release Time Rule
Alexander Johansson, Valerio Turri, Ehsan Nekouei +2
We consider a hub-based platoon coordination problem in which vehicles arrive at a hub according to an independent and identically distributed stochastic arrival process. The vehic…
Event-Triggered Distributed Model Predictive Control for Platoon Coordination at Hubs in a Transport System
Ting Bai, Alexander Johansson, Karl Henrik Johansson +1
This paper considers the problem of hub-based platoon coordination for a large-scale transport system, where trucks have individual utility functions to optimize. An event-triggere…
Multi-Fleet Platoon Matching: A Game-Theoretic Approach
Alexander Johansson, Ehsan Nekouei, Karl Henrik Johansson +1
We consider the platoon matching problem for a set of trucks with the same origin, but different destinations. It is assumed that the vehicles benefit from traveling in a platoon f…
Real-Time Cross-Fleet Pareto-Improving Truck Platoon Coordination
Alexander Johansson, Jonas Mårtensson, Xiaotong Sun +1
This paper studies a multi-fleet platoon coordination system in transport networks that deploy hubs to form trucks into platoons. The trucks belong to different fleets that are int…
Game Theoretic Models for Profit-Sharing in Multi-fleet Platoons
Alexander Johansson, Jonas Mårtensson
Profit-sharing is needed within platoons in order for competing transportation companies to collaborate in forming platoons. In this paper, we propose distribution models of the pr…
Strategic Hub-Based Platoon Coordination under Uncertain Travel Times
Alexander Johansson, Ehsan Nekouei, Karl Henrik Johansson +1
We study the strategic interaction among vehicles in a non-cooperative platoon coordination game. Vehicles have predefined routes in a transportation network with a set of hubs whe…
Optimal Weight Allocation of Dynamic Distribution Networks and Positive Semi-definiteness of Signed Laplacians
Jieqiang Wei, Alexander Johansson, Henrik Sandberg +2
In this paper, we consider the robustness of a basic model of a dynamical distribution network. In the first problem, i.e., optimal weight allocation, we minimize the H-inf- norm o…
Optimization of the -norm of Dynamic Flow Networks
Alexander Johansson, Jieqiang Wei, Henrik Sandberg +2
In this paper, we study the -norm of linear systems over graphs, which is used to model distribution networks. In particular, we aim to minimize the -norm subje…
