Abstract:

In order to optimize the configuration of large medical equipment in hospitals, improve the use efficiency, and avoid issues such as idle waste and repeated purchases of equipment, a method for evaluating the use efficiency of large medical equipment based on cloud models and the improved evidence theory was proposed, taking MRI equipment from 14 hospitals as examples. First, an evaluation index system is constructed for the use efficiency of large medical equipment from three dimensions: operational efficiency, social benefits, and cost control. Then, the cloud model is applied to generate the membership degree of each evaluation index and convert it into a basic reliability allocation function. Afterwards, in order to reduce the conflict between evidence, the evidence theory is improved based on the game theory. The dynamic and static weights are integrated in the game, and the conflicting evidence is identified, corrected, and fused through the combination of weight values. Finally, by referring to the idea of average fit, the closeness values of the evaluated object is compared with the optimal and worst solutions, to obtain a comprehensive evaluation result. A comparison of the cloud model fuzzy comprehensive evaluation method with the cloud model traditional evidence theory indicates that this method has advantages in solving evidence conflicts and handling uncertainty problems, providing decision-making basis for improving the efficiency of large-scale medical equipment use and optimization configuration.

摘要：

为优化医院大型医疗设备配置，提高使用效率，避免设备闲置浪费、重复购置等问题，以14家医院MRI设备为例，提出了基于云模型和改进证据理论的大型医疗设备使用效率评价方法。首先，从运行效率、社会效益和成本管控3个维度，构建大型医疗设备使用效率评价指标体系；其次，应用云模型生成各评价指标隶属度，并转化为基本信度分配函数；再次，为降低证据间冲突，基于博弈思想改进证据理论，将动、静态权重进行博弈组合，通过组合权重值识别冲突证据并进行冲突修正和融合；最后，参考平均贴合度思想，比较评价对象与最优、最劣解的贴近值，从而得到综合评价结果。与云模型-模糊综合评价法和云模型-传统证据理论进行对比验证，该方法在解决证据冲突性和处理不确定性问题中具有优势，为提高大型医疗设备使用效率、优化配置提供决策依据。
