DAYDREAMS
The overall Daydreams objective is to move forward the integration and use of data and artificial/human trustworthy intelligence together with context-driven HMI for prescriptive Intelligent Asset Management Systems (IAMS) in railway by:
- Advancing in maintenance approach towards prescriptive asset management;
- Improving the decision-making process by developing multi-objective decision optimisation approaches taking into account all implications of IAMS decisions in the railway environment;
- Reinforcing the role of the person-in-the-loop by designing and developing advanced context-driven HMIs to allow context- and risk-aware multiple-options decision-making processes.
The DAYDREAMS project will achieve its Scope through the following main objectives:
- Advancing in maintenance approach by moving from preventive and predictive asset management towards prescriptive asset management;
- Largely improving the decision-making process by developing multi-objective decision optimisation approaches thus taking into account all possible (often conflicting) implications of IAMS decisions in the railway environment (e.g., on Traffic Management System, Energy, Freight, etc.);
- Reinforcing the role of the person-in-the-loop by designing and developing advanced context-driven Human Machine Interfaces (HMIs) to allow context- and risk-aware multiple-options decision-making processes supported by the information on data sensitivity and robustness.
The HMI will allow the person-in-the-loop to: Properly access and visualise predictions/metrics and models; Assess why and how the model predicts something (“opening the black-box”); Steer models by setting parameters; evaluate alternatives using parameter steering and extending this process through speculative execution.
