The Biosecurity Commons development team has made a number of changes and improvements to the Surveillance Design workflow which are now live.
Surveillance Design enables users to determine where to allocate resources for a biosecurity threat.
Improvements to the workflow have made the user experience more generalised and intuitive, while more configuration options are now available for both discrete sampling and continuous surveillance designs.
Updates include:
- The workflow has been deconstructed into three logical sections for each surveillance design type: “environment” – to describe how the surveillance is partitioned, and to define the threat occurrence likelihood at each partition; “parameters” – to describe discrete or continuous method parameters; and “allocation” – to configure parameters associated with finding an effective allocation of surveillance resources given a chosen optimisation objective and relevant budgetary or other constraints, or for analysing an existing surveillance allocation
- All designs (i.e. all discrete sampling and continuous designs) may be partitioned via grid-based rasters, point-based locations (CSV), or other aspatial/division-based partitions (also CSV). Previously these options were limited within different design types.
- Point and aspatial CSV parameter inputs have become more flexible. Each parameter may be included in a single CSV file (defined within the environment) or may be defined separately. Previously, only a single CSV could be defined for sampling designs.
- Many design parameters may be optionally defined as a single value for the entire study or a separate value at each location or division.
- Optimisation options have been extended to include the minimisation of costs, the maximisation of monetary savings or non-monetary benefits, the maximisation of the total number detected (new), or the maximisation of the overall system-wide sensitivity (or probability of detection)
- Existing surveillance allocations may now be temporal (i.e. changing across time), so as to calculate temporal sensitivities, which may be utilised directly in proof of freedom workflows.
