Embodiments relate to supporting a decision making process. The method generates a graph that represents a decision making process. The graph comprises a plurality of nodes and a plurality of edges connecting the nodes. The nodes represent local decisions contributing to a global decision of the decision making process. Each node is associated with one or more parameters used for modeling the local decision. Each edge is associated with one or more parameters used for defining a relationship between two nodes. The method simulates the graph based at least in part on the parameters of the nodes and edges to derive an output global decision of the decision making process. The method receives a change to at least one of the parameters of the graph from a user and simulates the graph based at least in part on the at least one changed parameter to determine that the output global decision changes.
