AFRY Intelligent Scenario Modelling is a powerful and flexible software tool for creating dynamic models and performing deterministic or probabilistic simulations. AFRY Intelligent Scenario Modelling can be used for conducting risk assessments of complex dynamic systems evolving over time with any number of species. AFRY Intelligent Scenario Modelling has specialised databases and other add-ons designed for the field of radiological risk assessment.

The AFRY Intelligent Scenario Modelling license includes the ODE Toolbox and the additional toolboxes can be purchased at additional cost. Below is a list and short descriptions of the toolboxes:
ODE Toolbox: The ODE toolbox allows the user to create and simulate compartment models in AFRY Intelligent Scenario Modelling. Both linear and non-linear systems of ordinary differential equations are supported.
Sensitivity Analysis Toolbox: The Eikos Sensitivity Analysis Toolbox supports “state of the art” sensitivity analysis methods (local as well as global). Sensitivity Analysis is used to assess the influence of model parameters on model predictions.
Parameter Database Toolbox: The Parameter Database Toolbox provides a connection between AFRY Intelligent Scenario Modelling and its parameter database (Facilia Parameter Database).
Radionuclide Toolbox: The Radionuclide Toolbox is a plug-in for AFRY Intelligent Scenario Modelling for modeling of radionuclides. The Radionuclide Toolbox features a database containing all nuclide isotopes and their decay constants and energies. It also contains the parent-daughter relationships between a radionuclide and its decay products.
ODE toolbox
ODE toolbox
The ODE toolbox allows for creation and simulation of compartment models in AFRY Intelligent Scenario Modelling. Both linear and non-linear systems of ordinary differential equations are supported.
AFRY Intelligent Scenario Modelling Commercial and Academic licenses include the ODE toolbox.
This toolbox adds the following functionality to AFRY Intelligent Scenario Modelling:
The compartment building block representing a dependent variable or state.
The Transfer building block to model fluxes between compartments. Transfers can be linear, non-linear or discrete.
The transport sub-system which allows you to approximate partial differential equations in one dimension.
AFRY Intelligent Scenario Modelling primary use has been in conducting safety and risk assessments in the nuclear industry. However, it is a versatile software tool which has the potential to be applied across many other industries.
Nuclear Industry
AFRY Intelligent Scenario Modelling wide array of high-powered capabilities have assist in developing safety justifications for licensing of nearly all types of radiological and nuclear facilities and activities.
Mining Industry
AFRY Intelligent Scenario Modelling has been applied to the mining sector in the past, but on a client/contract specific basis. The traditional customer in this sector is user of AFRY Intelligent Scenario Modelling (or Normalysa), when it comes to activities to be implemented at uranium (and other element) mining and legacy sites. There is a need and potential for safety/risk/environmental impact assessments regarding radionuclides in NORM industries such as copper and other non-uranium mining sites.
The goal is to create models specific to the activities of a mine and its remediation which would be included into the model library and sold to customers as a specific product in conjunction with the AFRY Intelligent Scenario Modelling software license. Such models are expected to include:
Water balance; and
Chemical dispersal in the environment.
Contaminated land clients
In association with the aforementioned market segments, the contaminated land market would benefit from models including assessment of impacts of chemical or other hazards (biological, etc.) to the environment. Such models can be developed and included into the model library, for instance, for chemical transfer in connection to traditional waste management (landfills, etc.).
