What-If Analyzer for DMN-based Decision Models

This paper describes a new web-based graphical tool “What-If Analyzer for Decision Modeling” that supports what-analysis of different business decision models created in accordance with the DMN standard. It allows a user to modify the decision model by activating/deactivating business rules that represent its decision logic, and immediately see changes in the decision variables. With a simple click it may produce and navigate through multiple decisions that satisfy all active rules within the same decision model. If the decision model specifies a business objective that depends on other decision variables, then What-If Analyzer may find optimal decisions that minimize or maximize this objective. What-If Analyzer is implemented as an advanced component of the popular open source business decision management system “OpenRules”.
