MISTRALMulti-scale Infrastructure Systems Analytics
The aim of the MISTRAL programme is to develop and demonstrate a highly integrated analytics capability to inform strategic infrastructure decision making across scales, from local to global.
MISTRAL will thereby radically extend the ITRC’s pioneering infrastructure systems analysis capability:
• Downscale: from ITRC’s pioneering representation of national networks to the UK’s 25.7 million households and 5.2 million businesses, representing the infrastructure services they demand and the multi-scale networks through which these services are delivered.
• Upscale: from the national perspective to incorporate global interconnections via telecommunications, transport and energy networks.
• Across-scale: to other national settings outside the UK, where infrastructure needs are greatest and where systems analysis represents a business opportunity for UK engineering firms.
Challenge 1: The local complexity of national infrastructure
• Household scale demographic simulation
• Building characterisation
• Street-scale network representation
• Distributed renewables and storage
• Heat and hydrogen networks
• Explicit representation of the transport network
• Local flood and drainage simulation
• Solid waste transport and processing
• Mapping of digital services and needs
• Spatial allocation of infrastructure
High resolution at a national scale
Informing local innovation and devolved governance of infrastructure
Challenge 2: National infrastructure in an inter-connected world
Global interconnection of UK infrastructure:
• Energy
• Transport
• Digital communications
• Solid waste
Global network analysis
Analysis of infrastructure risks globally
NISMOD-Int: A transferrable platform for infrastructure assessment
DAFNI: the Data and Analytics Facility for National Infrastructure
DAFNI is an £8million new national research facility for infrastructure systems analysis, modelling, simulation, visualisation and decision support
DAFNI will be comprised of:
1. The national infrastructure database
2. National infrastructure modelling, simulation and visualisation facilities
DAFNI will be delivered by STFC and hosted at the Rutherford Appleton Laboratory in Harwell
Additional investment in computer hardware (including visualisation facilities) within UKCRIC partner universities will help to optimise the use of DAFNI
The National Infrastructure DatabaseDAFNI will provide • a secure facility for assembling, hosting and
creating datasets on infrastructure assets and networks and the human and natural environments in which they are located.
• management of licence arrangements, and a commitment to Open Data, as far as possible
• tiered security arrangements• metadata listing
The National infrastructure modelling, simulation and visualisation facilitiesThe DAFNI modelling and simulation platform will provide an e-science environment that will:
• interface with the National Infrastructure Database
• provide many-task computing facilities
• facilitate coupling of simulation modules to enable system-of-systems simulation
• link with visualisation facilities to enablescrutiny and communication of complexand high dimensional simulation results.
DAFNI Delivery and operation plan• Consultation on requirements during Year 1
• Initial hardware investment
• Pilot projects, starting with the migration of NISMODv1 to DAFNI
• ‘Crowding in’ of models and datasets
• A growing number of users in industry and government
• A sustainable long term business model will be put in place for operation, maintenance and upgrade of DAFNI from 2021
