Models ~ resilientCommunity
omf.models.resilientCommunity is a new model currently under development. Check back in the coming months for updates!
(Describes the purpose of the model and the use cases it was developed to address.)
Social vulnerability is a concept that provides a comprehensive overview of the factors influencing community resilience in the face of disasters. It highlights the importance of understanding vulnerability beyond physical infrastructure damage to encompass societal elements such as socioeconomic status, demographics, and access to resources. By recognizing these social dimensions, omf.models.resilientCommunity enhances disaster preparedness and response efforts to better support communities disproportionately affected by disasters. This introduction sets the stage for exploring how social vulnerability assessments can inform mitigation strategies and promote equitable resilience across diverse populations.
This model uses data from Federal Emergency Management Agency National Risk Index (FEMA NRI) that contains information for each census tract regarding relative risk indices, percentiles, and ratings that summarize:
- Social vulnerability
- Community resilience
- Risk of severe weather (e.g. wildfire, ice storm, hurricane, lightning, heat/cold wave, etc.)
- Expected financial loss due to natural hazards.

omf.models.resilientCommunity can be used to:
- Assess community need during emergency preparedness planning
- Decide how many emergency personnel are required to assist people.
- Identify areas and pieces of equipment in need of assistance in emergencies.
- Create a plan to evacuate people, accounting for those who have special needs, such as those without vehicles, the elderly, or people who do not speak English well.
- Identify communities that will need continued support to recover following an emergency or natural disaster.

Model Requirements
For the resilientCommunity model, users must specify whether they want to include Lines, Transformers, or Fuses within the analysis.
As well as whether there should be a data refresh, this is where the associated Fema NRI File should be updated or not
The “Loads Coloring By” selection is optional and up to the user to select from the following choices.
various options for loads coloring by

The Base Criticality Score (BCS) is an estimation representing the impact to a community should that equipment lose functionality leading to outage for downline loads.
It currently reflects the number of individuals served by a piece of equipment within an electrical system. This value is given either as a Base Criticality Score, which is a raw count of total individuals served, or by a Base Criticality Index (BCI), which is a percentile value determined by comparing the BCS’s for all circuit equipment to one another and ranking them from 1 to 100, where 1 represents the lowest criticality and 100 represents the highest criticality.
<----->USE LATEX FOR THE EQUATIONS
The Base Criticality Score for a load is calculated by the following :
The Base Criticality Score for a piece of equipment is calculated by the following :
The Community Criticality Score (CCS) is an estimation that is similar to the BCS, but weighted according to the associated social vulnerability score from the relevant census tract.
This value is given either as a score which is a raw count, or as an index, which is a percentile value
