Il monitoraggio dei processi aziendali è diventato sempre più complesso al giorno d’ oggi dal momento che i processi non avvengono più all’ interno di una singola organizzazione ma ne coinvolgono di molteplici. Nell’ ambito della smart logistics diverse sono le soluzioni che affrontano il problema del monitoraggio dell' intera supply chain con risultati più o meno discreti. In questo contesto l’ artifact-driven monitoring si presenta come una soluzione innovativa che sposta la fase di monitoraggio direttamente sugli oggetti interessati durante il processo, grazie all'utilizzo dell'\gls{iot}, consentendo di avere una piattaforma di monitoraggio flessibile e scalabile. Malgrado gli sforzi però un problema rimane ancora aperto: come stabilire una relazione di fiducia tra gli oggetti coinvolti all’ interno del processo che potrebbero essere manomessi da un' organizzazione coinvolta al fine di nascondere comportamenti anomali. Questo problema può essere affrontato tramite l’ impiego di una nuova tecnologia: la blockchain. Grazie alle sue proprietà la blockchain può offrire un ambiente distribuito in cui gli smart objects coinvolti possono registrare su di essa e quindi tenere traccia di tutti i cambiamenti di stato del processo multy-party secondo l' approccio artifact-driven. In questa tesi viene portato avanti uno studio esplorativo sul’ adozione della blockchain nell’ ambito della smart logistic, proponendo tre diverse soluzioni per affrontare il problema della trust prendendo come modello un processo appartenente all’ ambito della logistica e come piattaforma di monitoraggio l’ artifact-driven monitoring. Le soluzioni sono state implementate e testate al fine di ricavare dati utili riguardanti l' impatto economico delle suddette e i tempi di scrittura sulla blockchain.

Abstract
The monitoring of business processes has become increasingly complex nowadays, since processes no longer occur within a single organization but involve multiple parties. In the field of smart logistics, there are several solutions that tackle the problem of monitoring the whole supply-chain with discrete results. In this context, \textit{artifact driven monitoring} is presented as an innovative solution that moves the monitoring phase directly on the objects involved during the process, thanks to the use of \gls{iot}, allowing a flexible and scalable monitoring platform. Despite the efforts a problem remains open: how to establish a relationship of trust between the objects involved in the process as they could be counterfeited by a party to hide misbehaving. This problem can be addressed through the employment of a new technology: the \textit{blockchain}. Thanks to its properties, the blockchain can offer a distributed environment in which the smart objects involved can record and track all the status changes of the objects involved in the multi-party process according to the artifact-driven approach. In this thesis an exploratory study is carried out on the adoption of blockchain in the field of smart logistic, proposing three different solutions to tackle the problem of trust taking as a model a process belonging to the field of logistics and as a monitoring platform the artifact-driven monitoring. The solutions have been implemented and tested in order to obtain useful data regarding the economic impact of the above and the writing times on the blockchain.| File | Dimensione | Formato | |
