针对粗糙集在非决策系统评价中的局限性,提出了一种基于粗糙熵的武器系统效能评估模型.论述了该模型的评估步骤,并结合实例进行了分析.结果表明,基于粗糙熵的评估模型有效、可行,解决了原有评估中存在的问题,提高了武器系统评估的客观性和正确性,为武器系统的发展论证和实际使用提供了科学的理论决策依据. Aiming at the limitations of rough sets in the evaluation of non-decision system, a model of weapon system effectiveness evaluation based on rough entropy is proposed, and the evaluation steps of the model are discussed with examples.It shows that the evaluation based on rough entropy The model is effective and feasible, solves the problems existing in the original assessment, improves the objectivity and correctness of the weapon system assessment, and provides a scientific theoretical basis for the development demonstration and actual use of the weapon system.
