Empirical Dataset for the Comprehensive AVSEC Decision-Support Model: Košice International Airport (2025)

This dataset contains aggregated operational and contextual data used for a fuzzy multi-criteria assessment of aviation security at Košice International Airport, Slovakia. It includes 40 records, primarily covering 1 January–31 December 2025; one non-model contextual record refers to March 2026. The Excel workbook provides raw data, model parameters, 21 data-supported criteria across six AVSEC groups, calculated group and integral results, sensitivity analysis, and a data dictionary. Twenty unsupported criteria were excluded without imputation or simulated values. The principal integrated index is 0.8155, corresponding to a high level for the observed criterion subset. No retained group or criterion falls below the 0.50 problem threshold. The dataset contains no personal identifiers or restricted security information and must not be interpreted as an official AVSEC audit or a complete assessment of the airport’s AVSEC system.
