OpenMORDM is an open-source R library for Multiobjective Robust Decision Making (MORDM). Core features include:

  1. Connecting to models written in R or compiled as executables;
  2. Defining uncertain and deeply uncertain model inputs;
  3. Evaluating the model across many hypothetical states of the world (SOWs);
  4. Identifying potential robust designs using customizable robustness criteria;
  5. Characterizing vulnerabilities of designs using PRIM or CART;
  6. Evaluating tradeoffs among designs using various visualization tools; and
  7. An interactive, web-based visualization toolkit for sharing results
