[[alternative]]THE STUDY OF THE CAUSES OF AIRCRAFT INCIDENT USING GREY RELATION ANALYSIS--AN EXAMPLE OF AIR FORCE MODERN FIGHTERS

[[abstract]] 現代戰機具高科技、高造價、結構繁雜、系統複雜與品質要求高標準之特色，有關維修作業規劃，將直接影響戰機成軍服役期間之妥善情況。灰色關聯模型能將系統內各因素間灰色關聯清晰化，找出影響目標值的重要因素。 本研究經灰色關聯模型實證結果，得知在人為因素中影響最大為停機線人員檢查疏忽、修護人員操作不當及地面管制不當等；在機械因素中影響最大為材料疲勞、設計不良、機械磨損、腐蝕或銹蝕及燃油系統等；在環境因素中影響最大為助航設施、天候氣象及鳥擊意外等。 綜言之，本研究嘗試從戰機危險事件中找出飛行安全之影響因素，作為提供機隊管理及後勤維修管理階層決策之參考。關鍵詞：灰色關聯模型、危險事件、飛行安全。[[abstract]] The modern aircrafts are characterized with high-technology, high-price, sophisticated structure, complex system and high-quality requirements. The maintenance planning is the crucial factor that affects the combat readiness ratio of the aircrafts during the service life. The Grey Relation Analysis is able to clear up the grey relations between each factor and find the most important one toward the target object. By using Grey Relation Model, the empirical results conclude that the most important factors within the three types of influential factors are: (1) maintenance personnel negligence, repair personnel non-standard operation, and ground controller improper controls among human factors, (2) material fatigue, improper design, mechanic wearing, corrosion, and rusty among mechanic factors and (3) navigation-aid, weather, and bird-strike among environmental factors. To sum up, this study attempts to find the influential factors of flight safety from the dangerous incidents. The result provides the authority with a reference for making right decisions in logistics and maintaining fields
