Motor de fórmulas orientado a metadados e modelagem Typed EAV aplicados a um sistema de análise de impacto de explosivos

Abstract

The Bomb Squad of the Military Police of Paraná relies on interdependent mathematical formulas to define safety distances and estimate damage in explosive-related incidents. However, field operational support was carried out using spreadsheets, without access to organized records of previous occurrences, which undermined both the accuracy of calculations and the effectiveness of response in high-risk situations. This work presents Shockwave, a web-based decision support system developed to address this gap. The architecture combines Typed EAV modeling for dynamic attributes with strong typing, a metadata-driven formula engine with expressions defined in the database, and a computation graph with topological sorting for automatic dependency resolution. The system was validated across three operational scenarios - Bomb Threat, Located Object, and Post-Explosion - and its architecture allows new parameters and formulas to be added without source code modifications, providing flexibility for continuous evolution.
