Public Health Preparedness Models


This page is a list of computer models that have been developed for public health preparedness activities and are available for use by public health professionals. This page provides links to web sites for accessing the models and contacting those who developed them. Models are listed alphabetically within each category.

This page is not a list of government agencies, consultants, or research groups active in public health preparedness modeling. It does not include models that have been used in studies or developed by consultants but are not available freely for use by others.

Call Center Operations

Rocky Mountain Regional Health Emergency Assistance Line and Triage Hub (HEALTH) Model: web-based tool that estimates the potential surge of contacts needing staff to respond.

Call Center Calculator: web-based tool that estimates the number the of persons needed to answer calls in order to meet desired customer service levels.

cc-Modeler Lite: software that can determine the number of agents required to handle the incoming call volumes, while maintaining a particular average delay to answer.

Point of Dispensing

Bioterrorism and Epidemic Outbreak Response Model (BERM): allows planners to formulate realistic mass antibiotic dispensing and vaccination contingency plans for their target populations.
See also related models by the Cornell Institute for Disease and Disaster Preparedness.

Clinic Planning Model Generator: evaluates plans for mass vaccination or dispensing sites (PODs), including estimates of patient waiting time and staff utilization.

Clinic Surge Planning Model: for short-duration, high-volume clinics that have a surge of patients when the clinic opens.

Maxi-Vac: calculates staffing requirements and allocates staff for large-scale smallpox vaccination clinics.

RealOpt: includes simulation and optimization modules to determine staffing that optimizes performance in user-defined scenarios.

RealOpt Regional: identifies the best locations for multiple PODs.

Vaccine refrigeration planning model: determines the storage space needed to keep vaccine refrigerated.


SimPox: simulates the spread of smallpox and estimates the number of cases for each day of the attack.

Pandemic Flu

FluAid: provides a range of estimates of impact in terms of deaths, hospitalizations, and outpatients visits due to pandemic influenza.

FluSurge: estimates the number of hospitalizations and deaths of an influenza pandemic (whose length and virulence are determined by the user) and compares the number of persons hospitalized, the number of persons requiring ICU care, and the number of persons requiring ventilator support during a pandemic with existing hospital capacity.

FluWorkLoss: estimates the potential number of days lost from work due to an influenza pandemic.

InfluSim 2.1: predicts the course of an influenza epidemic in a fully susceptible population.

Vaccine Allocation Model is a Microsoft Excel workbook that can determine how many persons in different target groups can receive treatment if the number of vaccinations available is limited.

Evacuation Planning

Urban to Rural Evacuation Tool: presents statistical data for counties surrounding large cities where evacuations may occur in case of a terrorist attack or other disaster.

Casualty Assessment

EMCAPS: estimates casualties arising from biological (Anthrax, Plague, Food Contamination), chemical (blister, nerve and toxic agents) radiological (dirty bomb) or explosive (IED) attacks.

Decontamination Operations

Mass Casualty Detailed Decontamination Model: calculates decontamination throughput and decontamination site staffing.

RSS Operations

SNS TourSolver: web-based software for use by the Strategic National Stockpile for planning and managing distributions.
