Techniques for a modeling platform associated with simulating risk models. According to certain aspects, systems and methods include simulating the impact of qualitative assumptions on the risk model. Accordingly, the risk model may include a hierarchical tree formed of component qualitative assumption objects and quantitative assumption objects. Quantitative assumption objects include indications of distribution function parameters associated with the assumption object and qualitative assumption objects include an indication of an impact on a parent quantitative assumption. When simulating the risk model, systems and methods may adjust sampled values quantitative assumption object when a child qualitative assumption object is enabled.
