A WEB-BASED FUZZY AHP APPROACH APPLIED TO AEROENGINE HEALTH ASSESSMENT

摘要

Health assessment is an important technical measure for ensuring an engine's safe working and prolonging its operating life. This paper proposed a web-based system to overcome the obstacles of conventional health assessment of aeroengine with fuzzy analytic hierarchy process (fuzzy AHP), a commonly used tool for multicriteria decision making problems. Fuzzy concepts were integrated with real monitoring data to enrich the factors index. As an important part of aeroengine health management, the web-based framework is convenient for data collection, distributed management and processing. A case study was conducted in a fleet with ten aeroengines to validate the design of the system and its underlying fuzzy AHP model. Running results show the feasibility and reliability of the framework, which will be helpful to realize the quantitative analysis in aeroengine health assessment and provide a decision support tool for decision makers.
