“…In conventional data envelopment analysis (DEA), the absence of weight constraints on input and output variables compromises the model's ability to reflect the decision-maker's preferences 32 , 33 . Chames et al proposed the cone-constrained DEA model to address this limitation, which reflects the decision weights by adjusting the cone ratio 34 , 35 .…”

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.
