Abstract:
The study presents the development and implementation of a comprehensive information system for decision-making support based on classical criteria applied under uncertainty – Laplace, Wald, Savage, and Hurwicz. The system is designed as a tool for automating calculations, visualizing results, storing problem parameters, and ensuring increased accuracy in the analysis of alter- natives. This makes it effective for use both in the educational process, where it serves to demonstrate theoretical principles, and in applied analytical scenarios where rapid risk assessment, strategy comparison, and justification of an optimal choice are required. The system’s interface adaptation includes the introduction of a modern design, interactive graphical components based on Plotly, an optimized navigation structure, as well as support for data import and export in Excel format. This ensures conven- ience when working with large volumes of information and allows the user to quickly adjust problem parameters. The updated database structure includes new entities for storing the calculation history, problem parameters, and criterion types.
