This study develops and applies a multicriteria decision-support model to evaluate maritime patrol aircraft alternatives in the context of Brazilian Air Force strategic planning.
Design/methodology/approach
The study considers nine aircraft alternatives and ten quantitative evaluation criteria. Three Brazilian Air Force officers, including engineers and operations officers, participated in unstructured interviews to help identify and confirm the criteria and alternatives. Aircraft performance data were obtained from the Military Power database and cross-checked against information available on manufacturers’ websites. The Preference Selection Index (PSI) was used to derive objective, data-driven criterion weights, while the Combined Compromise Solution (CoCoSo) method was used to rank the alternatives. Sensitivity analysis was conducted using three values of the compromise parameter.
Findings
In the baseline scenario, the Kawasaki P-1 was the highest-ranked alternative, followed by the Tu-142 and the P-8 Poseidon. Although the final scores varied slightly across the three tested values of the compromise parameter, none of the alternatives changed position, indicating stability within the tested parameter settings.
Originality/value
The study’s contribution is primarily applied. It provides a transparent framework for preliminary screening of maritime patrol aircraft using quantitative and monotonic criteria when defensible subjective weights are unavailable, while explicitly recognizing that the framework is not a complete acquisition model.
