This study constructs a composite indicator system covering the core dimensions of medical equipment input and output. Based on this system, an innovative cone-constrained data envelopment analysis (DEA) model is designed. The model integrates the advantages of the analytic hierarchy process (AHP) with an improved criterion importance through intercriteria correlation (CRITIC) method to determine subjective and objective weights and employs game theory to obtain the final combined weights, which are further incorporated as constraints to form the cone-constrained DEA model. Finally, a bidirectional long short-term memory (Bi-LSTM) model with an attention mechanism is introduced for integration, aiming to provide a novel and practical model for evaluating the effectiveness of medical equipment. The proposed model has essential reference value for optimizing medical equipment management decision-making and investment strategies.

基于锥体约束DEA和基于注意力的bi-LSTM的医疗器械效能评估模型



本研究构建了覆盖医疗器械投入产出核心维度的综合指标体系。基于该系统,设计了一种创新的锥体约束数据包络分析(DEA)模型。该模型综合了层次分析法(AHP)的优点,通过标准间相关(CRITIC)方法改进了标准重要性,确定主客观权重,并利用博弈论得到最终的组合权重,并进一步将其作为约束条件,形成圆锥约束 DEA 模型。最后,引入具有注意力机制的双向长短期记忆(Bi-LSTM)模型进行集成,旨在为评估医疗设备的有效性提供一种新颖且实用的模型。所提出的模型对于优化医疗设备管理决策和投资策略具有重要的参考价值。
