液冷系统仿真模型置信度评估方法

基于典型架构的液冷系统，提出了基于三角模糊数的模糊层次分析法和相似度法相结合的液冷系统置信度评估方法。该方法利用模糊层次分析法，将液冷系统仿真模型分解为若干个部件级模型，使用相似度法计算各部件级模型中依据属性划分出的若干相似元的相似度。各相似元和各部件级仿真模型的权重，都利用模糊层次分析法进行计算获得。液冷系统总置信度由各部件级仿真模型的置信度和权重加权平均后计算得到，而各部件级仿真模型的置信度，则由各相似元的相似度和权重加权平均后计算得到。文中所建立的液冷系统置信度评估方法，结合了相似度法对复杂模型精准量化的优点和模糊层次分析法主观依赖性弱的特点，此方法科学有效，具有重要的工程使用价值。

Confidence Evaluation Method of Simulation Model for Liquid Cooling System

Based on the typical structure of liquid cooling system,a new method for evaluating the confidence of system simulation based on triangular fuzzy number and similarity method is proposed.In this method,the simulation model of liquid cooling system is decomposed into several component models by fuzzy hierarchy analysis method.According to each component simulation model,some similarity elements are determined.The similarity method is used to calculate the similarity degree of each similar element.The weight of similar elements of each simulation model is calculated by using fuzzy hierarchy analysis method.The confidence of each component simulation model is obtained by weighted average method.Based on the confidence and weight of each component simulation model,the total confidence of the whole simulation model of liquid cooling system is obtained by weighted average method.The method makes full use of the advantages of less subjective dependence of fuzzy hierarchy analysis method,and uses similarity method to accurately quantify the complex model.The confidence evaluation method of liquid cooling system is scientific and effective,which has important value in engineering.
