ORD - Open Results Data#

On this page:#


Introduction#

ORD was initially developed during the Lloyd’s Lab innovation project (Cohort 3) in 2019, by a working group led by Oasis, that focussed on constructing model agnostic results formats and appropriate data formats. These model outputs cover an extensive suite of results that can be isolated by aspects of the exposure data, financial and statistical perspectives.

Like OED, the purpose of ORD is to ensure model outputs are consistent, transparent, and model agnostic. The ORD package is intended to contain the outputs of all current catastrophe models and to be extensible to cope with future developments. The ORD outputs are results tables that capture all of the possible data that a model could produce.

Listed below are the different result tables.

Note

A model may not produce every result table; some may not be applicable from that scenario. However, this package covers an extensive suite of model outputs for multiple perspectives and calculations. All the outputs are available in order to cater to all model types and ensure continued interoperability.

The results can then be used to enable users to conduct comprehensive catastrophe risk analysis, quantify potential losses, and make informed risk management decisions. Results can be generated at a variety of summary levels, including single-way summaries and multi-way summaries. The way such complexity is represented in ORD is shown in the following example:


ORD summary levels example#

Consider an analysis run where the following output summaries are selected:

  • Summary 1: Single way summary of results by OccupancyCode

  • Summary 2: Single way summary of result by ConstructionCode

  • Summary 3: Multi-way summary of results by CountryCode x AreaCode x LOB

This is represented as follows (using mean and SD as a proxy for any kind of results). On the left are the link files and on the right are the summary files.
