DISIT Lab overview


Work at DISIT PhD grant, for 3 years at DISIT lab UNIFI on national PhD AI training course, 2024-2028

ITA: Sistemi modellistici per l’analisi della mobilità in organizzazioni complesse

ENG: Modeling systems for the analysis of mobility in complex organizations

ITA: Il dottorando svilupperà modelli per l’analisi della mobilità a partire da dati eterogenei a livello nazionale. Questi dati potranno essere elaborati con tecniche di AI/XAI per derivare informazioni di origine destinazione, ma anche per la valutazione dei servizi e la loro pianificazione. La principale tematica è relativa alla valutazione della soddisfazione della domanda di mobilità (data dai dati di movimento delle persone) rispetto all’offerta (formalizzata tramite il trasporto pubblico di varia natura). I modelli di ottimizzazione saranno sviluppati tramite tecniche di generative AI. Il candidato potrà utilizzare le infrastrutture di calcolo del DISIT Lab Https://www.disit.org come https://www.Snap4City.org Le tematiche proposte sono volte ad apportare un significativo sviluppo della conoscenza matematica e informatica, negli ambiti di interesse del PNRR, in particolare in merito a grafi che modellano reti di trasporto. Lo studio degli aspetti teorici e pratici di questo tipo di strutture dati rientra nelle finalità del percorso di dottorato. Il dottorando avrà l’opportunità di lavorare con dati in possesso di FS e di sviluppare algoritmi e metodologie data driven nell’ambito della mobilità.  Il progetto è pertinente con i criteri di ammissibilità e in particolare favorisce l’interdisciplinarità, l'adesione a reti internazionali e l’intersettorialità promosse dal PNRR. 6 mesi di lavoro presso Ferrovie dello Stato

ENG: The PhD student will develop models for the analysis of mobility starting from heterogeneous data at a national level. This data can be processed with AI/XAI techniques to derive source-destination information, but also for the evaluation of services and their planning. The main topic is related to the evaluation of the satisfaction of the demand for mobility (given by the movement data of people) compared to the supply (formalized through public transport of various kinds). The optimization models will be developed using generative AI techniques. The candidate will be able to use the computing infrastructures of the DISIT Lab Https://www.disit.org as well as https://www.Snap4City.org  The proposed topics are aimed at bringing a significant development of mathematical and IT knowledge, in the areas of interest of the PNRR, in particular regarding graphs that model transport networks. The study of the theoretical and practical aspects of this type of data structures is part of the aims of the doctoral programme. The doctoral student will have the opportunity to work with data held by FS and to develop data driven algorithms and methodologies in the field of mobility.   The project is relevant to the eligibility criteria and in particular favors interdisciplinarity, membership of international networks and inter-sectorality promoted by the PNRR. 6 months of work at Ferrovie dello Stato
