What's New in BMDS 3.3

BMDS 3.3 contains significant “under-the-hood” improvements to the BMDS model code library. These improvements provide better overall performance, consistent results with previous BMDS releases, and better error management support. 

The updated model code library lays the foundation for future enhancements and additions to the BMDS Model Suite, most notably the capability to run BMDS models, potentially, on multiple operating systems.

An important enhancement for EPA users is support for OneDrive, EPA’s current Cloud storage solution. EPA's recent expansion of OneDrive backup for EPA computers highlighted the need for BMDS to support OneDrive-synced network directories. 

The BMDS Release History page contains a complete list of BMDS 3.3's fixes and enhancements.


Downloading

  • BMDS 3.3 is a Microsoft Excel-based application that runs on the Windows operating system. Follow the download procedure to ensure BMDS is properly installed. BMDS also requires the user to enable Excel macros on first startup. 
  • Developers can download the BMDS 3.3 model source code to build the model DLLs used to calculate dose-response results. 

Acknowledgements

The BMDS 3 application and software components are the result of a collaborative effort between EPA , the National Institute for Environmental Health Sciences (NIEHS), and the National Institute for Occupational Safety and Health (NIOSH). 

The goal of the collaboration was to meet current dose-response needs of chemical risk assessors and introduce state-of-the-science dose-response methods, such as Bayesian analysis and model averaging.
