Research on the operational effectiveness evaluation method of shipborne small-caliber weapons based on AHP-Entropy weight method and fuzzy comprehensive evaluation

Shipborne small-caliber weapons play an irreplaceable role in maritime rights enforcement and patrol missions conducted by Coast Guard vessels. Given the wide variety of existing small-caliber weapons, some models must be phased out based on the functional requirements and developmental goals of Coast Guard operations, while others require further improvements in tactical and technical performance. Consequently, it is imperative to establish a scientific evaluation method for assessing the operational effectiveness of these weapons. This study proposes an equipment effectiveness evaluation model based on the AHP-entropy weight method and fuzzy comprehensive evaluation. The model constructs an index system covering reliability, maintainability, combat capability, environmental adaptability, human-machine interaction, and cost-effectiveness. By fully utilizing objective factors from secondary indicators and combining subjective and objective weights, the evaluation results better reflect practical conditions. Focusing on three types of weapons, the paper compares their comprehensive operational effectiveness through case analysis. The findings offer theoretical references for decision-making in the configuration and modernization of shipborne small-caliber weapons.
