Application of Fuzzy Data Fusion based on AHP in Health Evaluation of Diesel Engine Cooling System

摘要：

In this paper,the theory based on multi-sensor information fusion for the health condition evaluation of watercraft diesel engine cooling system is studied. The concept of health degree is defined,which is used as a quantitative index for evaluating the health condition of the watercraft diesel engine cooling system. The method of fuzzy data fusion is used to calculate the health degree,in this method the weight of each monitoring sensor is calculated by AHP (Analytic Hierarchy Process),then,the multi-sensor data are fused by the fuzzy comprehensive evaluation method. Base on these,the health condition evaluation system of watercraft diesel engine cooling system is set up.
