A system for fully integrated predictive decision-making and simulation having a high-volume deep web scraper system, a data retrieval engine, a directed computational graph module, and a decision and action path simulation engine. The system receives an analysis campaign configuration comprising analysis parameters for optimizing a decision; retrieves operations data from devices related to the analysis campaign configuration; retrieves supplemental data from deep web extraction related to the analysis campaign configuration; constructs a directed computational graph from the analysis campaign configuration; determines a set of possible prospective actions; simulates the outcome of each prospective action using the data processing pipelines of the directed computing graph as a simulation model; determines an optimal outcome from the parametric analysis by matching the outcome of each prospective action against the analysis parameters; and recommends the prospective action with the optimal outcome as the decision.
