Bike3S: A Tool for Bike Sharing Systems Simulation

no code implementations24 Jan 2024 Alberto Fernández, Holger Billhardt, Sascha Ossowski, Óscar Sánchez

The simulator performs semi-realistic simulations of the operation of a bike sharing system and allows for evaluating and testing different management decisions and strategies.

Streamlining Advanced Taxi Assignment Strategies based on Legal Analysis

no code implementations22 Jan 2024 Holger Billhardt, José-Antonio Santos, Alberto Fernández, Mar Moreno, Sascha Ossowski, José A. Rodríguez

In recent years many novel applications have appeared that promote the provision of services and activities in a collaborative manner.

Smart Recommendations for Renting Bikes in Bike Sharing Systems

no code implementations22 Jan 2024 Holger Billhardt, Alberto Fernández, Sascha Ossowski

Then, we go one step further, defining a strategy that recommends stations by combining the utility of a particular user with the utility of the global system, measured in terms of the improvement in the distribution of bikes and slots with respect to the expected future demand, with the aim of implicitly avoiding or alleviating balancing problems.

Agreement Technologies for Coordination in Smart Cities

no code implementations21 Jan 2024 Holger Billhardt, Alberto Fernández, Marin Lujak, Sascha Ossowski

In this paper, we argue that agreement technologies are a suitable means for achieving coordination in smart city domains, and back our claim through examples of several real-world applications.

Taxi dispatching strategies with compensations

no code implementations21 Jan 2024 Holger Billhardt, Alberto Fernández, Sascha Ossowski, Javier Palanca, Javier Bajo

The advance of ICT and geo-positioning systems has given rise to new opportunities for improving the efficiency of taxi fleets in terms of waiting times of passengers, cost and time for drivers, traffic density, CO2 emissions, etc., by using more informed, intelligent dispatching.

Legal and ethical implications of applications based on agreement technologies: the case of auction-based road intersections

no code implementations18 Jan 2024 José-Antonio Santos, Alberto Fernández, Mar Moreno-Rebato, Holger Billhardt, José-A. Rodríguez-García, Sascha Ossowski

Agreement Technologies refer to a novel paradigm for the construction of distributed intelligent systems, where autonomous software agents negotiate to reach agreements on behalf of their human users.

mdendro: An R package for extended agglomerative hierarchical clustering

no code implementations23 Sep 2023 Alberto Fernández, Sergio Gómez

"mdendro" is an R package that provides a comprehensive collection of linkage methods for agglomerative hierarchical clustering on a matrix of proximity data (distances or similarities), returning a multifurcated dendrogram or multidendrogram.

Spillover Algorithm: A Decentralized Coordination Approach for Multi-Robot Production Planning in Open Shared Factories

no code implementations14 Jan 2021 Marin Lujak, Alberto Fernández, Eva Onaindia

Open and shared manufacturing factories typically dispose of a limited number of robots that should be properly allocated to tasks in time and space for an effective and efficient system performance.

Versatile linkage: a family of space-conserving strategies for agglomerative hierarchical clustering

1 code implementation21 Jun 2019 Alberto Fernández, Sergio Gómez

Agglomerative hierarchical clustering can be implemented with several strategies that differ in the way elements of a collection are grouped together to build a hierarchy of clusters.
