Un salto di qualità nel sistema di trasporto pubblico è necessario per assicurare uno sviluppo sostenibile delle città che stanno diventando sempre più popolate. Negli ultimi anni, il generale incremento del benessere ha portato a una crescita del bisogno di mobilità e allo stesso tempo le persone hanno continuato ad alzare le loro esigenze relative al servizio offerto dal trasporto pubblico. Soddisfare le aspettative della clientela non è un compito semplice per le aziende di trasporto pubblico che sono obbligate ad operare in un ambiente nel quale le interazioni con fattori esogeni (disturbances, disruption events) generano molta variabilità nel servizio offerto ai passeggeri. La mancanza di adeguati sistemi per il supporto alle decisioni rende il lavoro degli operatori di sala operativa, che sono incaricati di mantenere un buon livello di servizio, ancora più difficile. Al giorno d’oggi le decisioni sono prese manualmente e per questo sono generate molte inefficienze. L’obiettivo di questa tesi è la creazione di un decision support system capace di prevedere situazioni critiche sulle linee e di suggerire soluzioni agli operatori di sala operativa. Il disruption management support system sarà diviso in tre parti principali: Data side, process side e additional information side. Questi tre componenti collaboreranno per offrire soluzioni ottimali. L’obiettivo finale del sistema sarà dare suggerimenti agli operatori per massimizzare la service reliability (travel time reliability + livello di comfort) senza compromettere gli altri aspetti considerati importanti dai passeggeri e in questo modo incrementare l’acquisizione e il mantenimento dei clienti.

Abstract
A quality leap in public transportation system is necessary to assure a sustainable development of cities that are getting more and more populated. In last years, a general increase of wealth brought to an increase of need of personal mobility and at the same time people kept on rising their requirements related to public transport system service’s quality. Meeting customers’ expectations is not an easy task for public transport operators because they are forced to work in an environment in which the interaction with external factors (disturbances, disruption events) generate a lot of variability in the process output (the various trips from stop to stop). The lack of adequate decision support tools makes the job of control room operators, which are in charge of keeping the service quality at a desirable level, even more difficult. Nowadays decisions are taken principally manually and due to the short sightedness of this approach, many inefficiencies are generated. The aim of this thesis is the creation of a decision support system able to foresee critical situations and to give suggestions to control room operators. The disruption management support system will be divided in three main parts called: data side, process side and additional information side. These three components will work strictly together. The final objective of the system will be providing suggestions to dispatcher for maximizing the service reliability (travel time reliability + level of comfort) without compromising the other quality aspects considered important by passengers and in this way increasing their acquisition and retention.| File | Dimensione | Formato | |
