WP2: Asset ontology, system architecture and resilience framework
Objectives:
Produce an architectural specification of the TwinCity integrated platform that will be the basis for the technical developments in WPs 3-6, as well as for the integration and piloting activities in WP7. Select and survey the pilot study area. Setup a Geographic Information System to integrate all data.
Description of Work:
Task 2.1: Specification of system requirements & scenarios definition (All) A detailed specification of functional and non-functional requirements will be produced for the TwinCity integrated system. A specific study of the pilot area will be carried for a preliminary identification of the integration activities (e.g. deployment of new hardware, integration with legacy systems, etc.) that will be needed in WP7 for validating the system.
Task 2.2: Design of the overall system architecture (All) An architectural specification of the TwinCity system will be elaborated to matches the requirements specification. The specification will encompass the definition of the different modules/tools to be developed in WPs 3-6, the definition of a common information model for coordinating data sharing among these modules and with other external tools and systems, and the specification of a hardware & software interconnection layer to enable communication and interoperability with sensors and external data sources. In addition, a toolset will be specified for supporting the full development cycle, including a version control repository, testing tools, cloud hosting, etc.
Task 2.3: Definition of pilot area, assets, networks, interconnections and interdependencies (RED, NTUA) A pilot area will be selected from the Dodecanese islands. A full survey of residential, commercial, industrial, and heritage buildings will be performed, using satellite, cadastral and open-source data (e.g., OpenStreetMap). A three-tiered hierarchical classification will be employed in tandem with a detailed taxonomy definition to identify critical structures (Tier 1), eliminate structures of no interest (Tier 3) and classify the essential non-critical ones (Tier 2) into homogeneous classes. Simplified models will be built for networks modeling major arteries explicitly (Tier 1), and smaller branches in aggregate (Tier 2). Census data will be leveraged to distribute permanent residents and seasonal visitors (tourists), identify local businesses, their supply chain, and associated interdependencies. All results will be encoded in the GIS.
Task 2.4: Definition of digital-twinning compatible resilience framework (NTUA) A holistic risk assessment framework will be elaborated pertaining to how hazard, risk and impacts are propagated while keeping track of pertinent uncertainties and updating the estimates based on online data input. This will form the core of the CDT model, detecting the occurrence of events, tracking the failure and subsequent recovery of assets, and propagating the effects to other interconnected assets or networks. Throughout this process, updates will be applied, recalibrating the CDT as needed to match new input data streams and allow enhanced predictive capabilities.
